    i would say choose 8GB of ram vs 6 (2x4gb sticks) and can that board to SLI?

    does your video encoding use cuda, if so stick with nvidia. If not might aswell get the 6870/6950.

    PSU, for futures sake of crossfire/sli either a seasonic or corsair 850W PSU.

    everything else looks blessed.

    Yes for LGA1155 systems you want dual channel memory, not triple channel. I'd recommend going with:
    http://www.newegg.com/Product/Product.aspx?Item=N82E16820145324

    If you're not going to go with a Gigabyte, can I tempt you into an MSI board instead? It pains me to see someone opening themselves to the pain and suffering of owning an Asus board!
    As for the video card, whichever of these is the best you can afford [assuming you actually need this level of performance]
    HD6850
    HD6870
    HD6950
    HD6970

    Hi guys, i see that this thread has stopped for a while...but anyways, I have a few questions about power supplies and don't wanna create a new post on it.

    Anyways, right now i'm busy saving up for a new PSU, and i need your guys opinion on which one to get and which ones to stay way from. Here is the list of them:

    *Corsair CX600w
    *Corsair GS600w
    *CoolerMaster eXtreme power RS600w
    *CoolerMaster GX650w

    Thank you for your time, if you have other good PSU in the above mentioned PSU price range please feel free to let me know ^^

    Edit: Heres some extra info that might help:
    My current (outdated) system
    -Q9400 cpu
    -Biostar TPower P45 mobo
    -HD 4850 1Gb gpu
    -1x 500GB, 1x 1TB and 1x 250Gb hdd's
    -2 x 1GB ram

    will be upgrading the system soon tho, but first the PSU.

    What are you upgrading to? 600W is massive overkill for your current system.

    Of those units:

    Corsair CX 600W - crap, avoid
    Corsair GS 600W - No such thing
    coolermaster extreme RS 600W - avoid
    coolermaster GX 650W - not ideal, also avoid
    The best 600W PSUs right now are probably the Corsair TX 650W and the Seasonic X-650.

    There is Corsair GS 600w - http://www.corsair.com/power-supplies/non-modular-psus/gaming-series-1/gs600w.html
    hmm...i guess i'll take TX650w then

    Hopefully by the end of the year:

    Case - CM690 II Advanced
    CPU - Intel Sandy Bridge 1155 i5-2300 2.8GHz
    Mobo - Asus P8P67 P67 chipset ATX (Not sure)
    GPU - HD 6850 1Gb
    PSU - Corsair TX 650w
    RAM - Corsair Dominator DDR3 1600 2x2GB

    Edit: budget is under R8000, but can manage R10k

    So there is, that one passed me by. So far I can only verify the OEM quality of the 800W version, I wouldn't go advocating that unit until some more info comes in.

    P67A-UD3 or UD4, depending on whether or not you're going crossfire. Don't bother with Asus dirge.

    Well, if you're happy to pay extra for a black PCB, then go for it. There are other reasons to buy the UD4 too of course. Not sure if any affect you.

    HOLY SH!T there is!!!

    Even tho I like the PSU's you (SM) reccommended I'm sure the GS 600 might do as well. If no one is "allowed" to purchase it then how do we know what it's like. A simple search might be needed to find some feedback and see how it "fared". ;)

    OH.... and all costs AVOID anything with the ASUS moniker. They are the worst company on the planet. What BULLSH!T that is!!!!!!!!!!!!!!!

    A few reviews on the ASUS mobo you where looking at. ;)
