    What's in said computer?
    A Corsair HX 520W or 620W will suffice for all but the absurd, and the Zalman ZM-850HP or ZM-1000HP for the absurd.

    and What do u mean by absurd is it better if it's for absurd or if it's not for absurd?

    I had that power supply a little while back, and it's fine, but it's very expensive and over the top for most PCs, and it's also very noisy.

    You do NOT want a 780i motherboard. They are shockingly abysmal.
    Presumably you want dual graphics with a high end motherboard that will fit, in which case:

    Note - system memory and graphics memory types do not need to be the same - a GDDR3 graphics card does not need a motherboard with DDR3 support, they have nothing to do with each other. I use that graphics card and a very similar motherboard (the older X38 version) which is GDDR5 on a DDR2 board.

    I don't want that motherboard because i guess it only supports 1200 memory and im not into downclocking it cuz i want 1066 memory. Would this be any good power supply?
    http://www.newegg.com/Product/Product.aspx?Item=N82E16817139007

    and answer this u never did lol
    A Corsair HX 520W or 620W will suffice for all but the absurd, and the Zalman ZM-850HP or ZM-1000HP for the absurd. and what about the corsair hx 1000 i sent u a link up there. is it for the absurd? Is it better than the zalman ones and what's better about zalman or corsair if so? I know the 620 what won't handle dual or triple graphics cards.
    and What do u mean by absurd is it better if it's for absurd or if it's not for absurd?

    and any of these motherboards?

    It supports UP TO 1200mhz memory, which includes 533,667,800 and 1066.
    You don't need the HX1000W PSU.
    What I meant by the absurd comment is that a 520 or 620W PSU will be fine for almost any system unless it's completely insane.

    The graphics cards you have chosen are much slower than the HD4870X2 I chose, less than half as fast in fact.

    Since you're clearly a beginner at PC building what are you intending on using the PC for? I will give you a list of components that are most suited to that purpose.

    Also the 620w corsair probably won't handle daul graphic cards or triple for sure but maybe dual is that true? but I just want to know and the one u told me about ive heard it's required to have a 650w power supply is that true? Answer both and the above posts also the last 2 but im not planning on daul nor tripple anyways but i just want to know.

    And I believe the graphic cards i posted would be able to run crysis and other crazy requirements games on high settings. Would they? Ive heard the one u posted for 500$ struggles on crysis high setting. But not sure if that's true though.

    Please, use the post edit button in future.
    The 9800GTX is a really slow and old card compared to the 4870X2. The 4870X2 is the only card I would recommend to max out games at 2560x1600 (and it can do for the original Crysis, but not Warhead). The 9800GTX can only really pull off medium settings at a lower resolution like 1920x1200, and the 9800GX2 perhaps high, but still at the lower resolution. All depends on the monitor size you're using. You only really need the 4870X2 for a 30". However, I would still not buy the other cards you mentioned, as they are more expensive than a better performing card, the HD4850. If you use a 22" monitor, I'd recommend that:
    http://www.newegg.com/Product/Product.aspx?Item=N82E16814161244
    If you're using a 24", I'd go with this:
    http://www.newegg.com/Product/Product.aspx?Item=N82E16814125225
    The Rampage Formula is an excellent board, you are welcome to go with it, but it is expensive. The P5Q Pro is OK, but none of the P45 boards are perfect.
    The sound card you posted is very similar to this one:
    http://www.newegg.com/Product/Product.aspx?Item=N82E16829102002
    Which is a fraction of the price. it does all the same stuff, I should know, I owned one.
    I use a 520W Corsair HX with the 4870X2 I listed, it's not ideal, but it does work, so the 620W version will be ample for your system, there is no need to buy the 1000W unit.
    The RAM you have is excellent.
    The case is fine, but a similar looking case that is better designed, and to an extent better made is this one: http://www.newegg.com/Product/Product.aspx?Item=N82E16811146047
    Cooling performance is about the same, but this is a better platform to build a PC in.

    The Q9550 is fine as a CPU, the Q9650 will overclock further, but otherwise isn't worth the expense.
    I'd recommend this CPU cooler:
    http://www.newegg.com/Product/Product.aspx?Item=N82E16835154001
    these hard drives:
    http://www.newegg.com/Product/Product.aspx?Item=N82E16822136296 - for your OS
    http://www.newegg.com/Product/Product.aspx?Item=N82E16822136151 - for your data
    and this CD Drive:

    The 4870X2 is the only card I would recommend to max out games at 2560x1600 (and it can do for the original Crysis, but not Warhead) What is warhead? And do u mean it won't handle crysis warhead on high? What will it handle then on it; medium? What about the graphics cards u expect for me? Would the gx2 do high for both types of crysis? Well the other 2 graphics cards u posted seem to be the same thing except the cheaper ones has Superior IceQ4 cooling moves heat out of the case seems to be faster in memory clock and the more expensive one has more power connectors and is faster in core clock and I've been hearing that memory clock is more important than core clock so which of these would u really recommend? But thank you. And would u recommend me to get the motherbaord i chose or the ones u also said is fine? I see the one i chose doesn't support raid sata is that a problem can u make it support it by adding controllers or something? And the cpu 9550 in new egg comes with a cooler and im not an overclocker so ide get the q9550 and should i just change the cooler if i get it anyways? thanks. also what are the hard drives used for the OS and the data one I never heard of picking them for different things before and what's the rpm of the 1tb hard drive? and would the more expensive graphics card one for 280$ support and 19" panle? the case that u posted has has 1 external drive bay that the one i posted doesn't. and the case u posted has less expansion slots. what are expansion slots and what do they do and do they really matter because it has 6 of them and the one i posted has 7.

    Warhead is Crysis Warhead, as in the expansion.
    It (the 4870X2) will do fine on Gamer (High), but not Enthusiast (Very High).
    It will manage Enthusiast on any lower resolution like 1920x1200 no problem.

    So you can put ur graphics card and make it lower resolution? And then ull make it very high right? Would it be better for me to get this or this?
    http://www.newegg.com/Product/Product.aspx?Item=N82E16814161244
    http://www.newegg.com/Product/Product.aspx?Item=N82E16814125225

    and would any handle crysis warhead on high?

    And do the hard drive types really matter what is data and OS and what do u use each for and why did u pick me those drives? And can u find me anoter cd drive because the one u posted u have to sign up to buy it and e mail them. Thank You. btw would the PSU hx620 be able to connect to the video cards? Because it doesn't have any 6 pin connectors and the video card says power connector 6 pin. Or where do u connect the 6 pin to if it's not it? Or is it the same thing as pci express connector (is this 6pin+2?)? because it has 2 on the 620 and 6 6pin+2 on the 1000w one. And do they matter? because atleast the 620 one can handle the http://www.newegg.com/Product/Product.aspx?Item=N82E16814125225 graphics card. Can it?

    I'll re-state this as you don't appear to have noticed:
    You will only need to lower the detail or resolution if you use 2560x1600, which ONLY works on 30" PC monitors (very expensive) any smaller monitor, or any HDTV, and you will be able to run pretty much anything max with the 4870, you might have to adjust a few things with the 4850.

    The Corsair HX PSUs have 8-pin connectors, which are formed of 6-pins and two additional ones if required. The HX PSU can run these cards fine.
    I chose those specific hard drives as the 1TB Greenpower can store lots of data but isn't that fast. The Velociraptor can't store as much but is much quicker, so that's why I choose two separate drives. You can't get ultra high speed drives with any more than 300GB of storage, and I recommend having two hard drives in a powerful PC anyway to simplify data management.

    My mistake about the out of stock CD drive, here:
    http://www.newegg.com/Product/Product.aspx?Item=N82E16827136153

    I would strongly urge you get someone to supervise this build though, to make sure you do everything correctly. While building a PC isn't hard, you do need to pay attention.

    Well what you would urge me I'm going to actually not spend money for asking someone else to do it for me because I'm working on this with my big brother also. So i belive i can build it all myself. I'm 14 i can do it. So would the q9550 be the best choice if im not an overclocker since the c1 and the multiplier don't matter since im not an overclocker right? And don't think it will make a big performance difference with the q9650 (which uses e0 and higher multiplier) if im not an overclocker. Is that true? but will if i was to be. is it true?, but im not an overclocker. But i beleive after this post it's probably all the info i need. Would the 4870 be good for a 19" monitor? also so did u mean the 30" monitors can handle more resolution and more detail that the 4870 can't so it has to be lowered? The 4850 seems to have more cooling components such as Superior IceQ4 cooling moves heat out of the case does that make a big difference though? And 4870 has 200 mhz less memory clock and 100 mhz more core clock will that show any big difference and is that still considered that it's better and faster than the 4850? Because ive heard memory clock matters more than core clock. Is that true? And if it is how is the 4870 better since it has less memory clock more core clock (how does it still handle better)? If not true then still tell me how does the 4870 still handle better? And what really matters and what matters when picking a gpu? I know this is a lot of questions but probably if u answer all of these this is probably my last post; unless there more i need to know about. But thank you.

    If you're not overclocking (and I probably wouldn't recommend it at age 14) then the Q9550 will be ample for your system, it's a very powerful CPU.
    With regard to graphics cards, it all comes down to performance. Pretty much any cheap old graphics card can actually run Crysis at 2560x1600 with maximum settings, but the result of that will be that the frame rate (i.e. how many times what's on the screen changes per second) will be so low, the game will be less running around a smooth environment and more like watching a slideshow. The reason for buying a powerful graphics card is so that you can increase the resolution and detail level and the game will still be playable and smooth. If you're only ever going to use a 19" monitor, a card like the HD4850 will be ample, as the highest resolution a 19" monitor can usually display is 1680x1050, and that's rare, it's usually 1280x1024 or 1440x900. The 30" monitor I use at 2560x1600 has three times as many pixels, so therefore to play the same games at the same detail level looking like that, I need three times as much graphics power - which is roughly the difference from an HD4850 to an HD4870X2, a bit less, hence why I use one.
    The HD4850 has an ICEQ cooler because its heat output is low enough to allow third party manufacturers to produce coolers like that. The HD4870 produces more heat, and therefore only a few specific designs can actually cope - the ICEQs are more built for quietness than low temperatures.
    As far as the clock speeds of the cards go, they're completely irrelevant. Many cards have had faster clock speeds but been slower, the HD3870 was a good example. It's all about the internal design of the cards, how that speed is put to good use.

    There is no specification you really have to keep your eye on when buying graphics cards. All decent cards have at least 512MB of memory nowadays, and unless you use at least a 24" monitor, that's all you'll need. The rest of the specs are pretty much meaningless, you need to read up on specifically, which product is faster than the other, for example - the HD4870 being 20% faster than the HD4850 might be obvious, but the HD4850 beating the 9800GTX+? Not so obvious.

    Lastly, if you're buying a powerful high-spec gaming PC, I highly recommend getting a bigger monitor with nice keyboard/mouse to match. Honestly, it really does transform the experience.
