I got a Evga GTS450 and i was thinking about saving money and buy another one at the 400 series, but IDK if i can SLI the 480 or 460... Does it works or do i have to buy the same VideoCard? Also does the Memory and Core Clock matters when bridging(SLI)the videocard?

OK THANKS GUY... Also when it's SLI, does it share memory and speed and does it ganna work with my setup of 700W PSU, I listed most of my parts in the "Is i7 better or Q9550" thread...

No they don't share memory. It's not 2GB of video memory, it's 2 cards with 1GB each.
PSU will matter. What brand is your PSU, and if you can, tell us how many amps it has on the +12v rail.

They share the work load for graphic intense apps including games,one would assume faster processing since you'll have two gpu's working at the same time

It increases FPS by sharing GPU load. Think of it as a grid of squares on your screen. Each alternating square is rendered by one card. Each other square is rendered by the other card. In a perfect scenario it will double your FPS. But in real life it's usually 60-90% faster depending on the game.
Your PSU would definitely be an issue. It's cheap and is a low quality brand.
For 700W in a quality unit you should be paying more like 3 times that much. http://www.newegg.com/Product/Product.aspx?Item=N82E16817139006&cm_re=corsair-_-17-139-006-_-Product
I would definitely replace your PSU before getting 2 cards.
This would be perfect for your setup. http://www.newegg.com/Product/Product.aspx?Item=N82E16817139005&cm_re=corsair-_-17-139-005-_-Product

And i forgot to ask, what happens if i just put the Videocard in without a new PSU?

Well sorry dude but just telling it how it is. If it works you can keep using it, but it should be replaced before you put 2 video cards on it. Brands like that will pop and take other parts with them. I've seen it time and time again. The second you put heavy enough load on it, it will fail. Believe me I started PCs young as well and it's hard to get stuff together. One step at a time.
Something like 600W+ in good quality is really the minimum you should be using for long term reliability with 2 cards.

To answer your other question probably nothing right away. But the chance will always be there that you could overload the PSU. If it fails, it will probably take other stuff with it. Dead video cards and hard drives are not uncommon from a bad quality PSU.
I would guess a unit like that is actually doing more in the range of 450-500W, if that. And not good quality power either.

lol no that's quite a heavy system for such a low quality PSU. It's not a matter of how long it will last. It could fail at any time. And it will more than likely kill other stuff given it's low price. If you are planning to make an upgrade, sacrifice a bit on some other things to squeeze a better PSU in. Do not depend on it to last you for any length of time. I'm speaking from experience here. It WILL fail if you put a high end system on it.

Yeah no problem just trying to help :P Good luck getting your funsds together and I hope it all works out.
Something like a 22 inch at 1680 x 1050 or something similar would likely be a good match for your video card. Monitor brand isn't too important so just look for what matches your budget.

Like I say pick the one that works best for you. They're all more or less the same thing. High contrast and low response are good.

I just found my Bro's Power Supply for his computer... http://www.superbiiz.com/detail.php?p=PS-ST550AC&c=pw&hash=5840YoL1IfmpZYKC4M8qpo2prhHCUqAXPyxyeBu23qd%2B62nrKEJbL%2FvWWtUh%2FoYwu4PTRtrMhLvxypO0fBA8hE0lppAbqmwPPu2807nqu1JH930ao6wDRvGdOeU
It lasted a year and a half... It failed but didn't ake any stuff... Read my other thread to see problems with his computer... It died after 1 year and a haf and it's cheaper than mine... How is it possible that the computer still running with all those lights and without anything burning awhile it failed? It didn't take the stuff with it, it turns on but im guessing it's probably some wire failed...

As far as your Bro's power supply it was cheap crap plain and simple. 1.5 years is a terrible lifetime and he didn't lose anything because he was lucky. Power supplies are super important. My Seasonic built Corsair 620W has been running for 2 and 1/2 years now on everything from dual cores to my current overclocked quad core with 2 video cards. And for 620W it was $150.
And the video card yeah it will work. As long as the number is the same you are good to go. Getting an overclocked one won't help your speed though because they will both run the same as the slowest card in the pair.
