What kind of performance will I get on this new build?

The psu will be good enough and if you have an additional $20 you can consider going with this Ivy Bridge cpu;

$239.99
Intel Core i5-3570K Ivy Bridge 3.4GHz (3.8GHz Turbo) LGA 1155 77W Quad-Core Desktop Processor Intel HD Graphics 4000 BX80637I53570K

You've made some excellent choices for your budget. Here's my dvd burner if you want to save $8: http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Your other post has the GTX 560 and a Corsair 600w psu , so what are you going with for those components and why the two different posts?

i am going with this one if the 650 is powerful enough

The GTX 480 card requiremnet for a psu is 600w so a 650w psu is going to be good enough and the GTX 480 will do a good job with giving you some decent performance in the games that you want to play.

ok thanks

What fps could I get out of this?

Take care installing RAM into that motherboard. I had it but got it exchanged (not for this reason), and I noticed it's not quite ATX sized. It's got different stand off positions and it doesn't have much support when sticking RAM in. It's pretty flexible too.

You don't need to spend that much on the motherboard, get this instead.

Try getting a 700W PSU, 650 is tight when you SLI the GTX 480s.
Keep in mind that GTX 480s are notorious for being hot.

There are several factors involved in determining what you will get for FPS out of your computer.
First , the game that you are playing.
Second , the resolution on the monitor.
Third , the settings in the game.
Fourth , sometimes the cpu will be a determining factor.
Lastly the video card which is actually the most important part will have a huge part in what you will get.

So all of these things will determine what the FPS is that you will get , for example you want to play BF3 and you want to play at 1920x1080 and the in game settings are set to ultra , in this case the fps will be on the low side because you will be taxing the video card real hard and you might only get 25 fps which is barely playable. So then you would have to lower the in game settings to medium and the resolution to 1280x768 and you might end up with 35 to 40 fps which now becomes very playable.
The game COD MW3 is a different story because it's not as demanding a game so you can have the resolution set to 1920x1080 and the in game settings on high and be getting 60 fps and have great gameplay.
So because there are so many different combinations of cpu , gpu , ram and monitor resolution it's hard to say what you will be getting for fps and the only way to know is to run the game on your computer and see what you end up with and what kind of adjustments you will have to make. The good news is that you have a good video card and a good cpu so you should be getting some good gameplay and only with the most demanding games will you have to lower anything.

I don't think I will start with sli I will upgrade my psu when i do

should I get a evga 560 instead?

A GTX 480 for $200 is a very good (and hot) deal. But get the 560 Ti unless the 480 has a custom coooler (I'm looking at Gigabyte and MSI).
Or, if AMD is an option, get a Radeon 7850 with the $30 you saved on the motherboard. Runs much cooler and quieter. You could probably Quad-Crossfire them with a 650W PSU. And, it can match the performance of a GTX 580.

This graphics chart should help you see where cards fall in comparison between Nvidia and AMD.
The GTX 480 is two levels above the 560 and is at the moment one of the better deals going. When it was released the GTX was a flagship video card like the 580 was when it was released , while the 560 , 560Ti , 550Ti , 460 and others were not so a GTX 480 is a top quality card and would then perform better then the 560 and even the 560Ti and would be on the same level as the 570 but for a lot less money.

what is the best card for around $200?
the evga 480 is good but has a bad cooler

None besides the GTX480. However, if you can spend $50 more, get a 7850, it's at the level of a GTX580.

I can get a i5 3570k for less with a mobo combo for less than the i5 2500k

If so, then get it.
