If you want to get the best gaming performance switch out the SSD ($110 less) for a
i5-2400 ($65 more).
switch to a 6950 ($30 more) - http://www.newegg.com/Product/Product.aspx?Item=N82E16814150524
Antec Earthwatts 650 (same price after rebate) - http://www.newegg.com/Product/Product.aspx?Item=N82E16817371044
The final price should come out to be roughly the same.
The SSD will make the OS boot fast and a few games (whatever fits in 30GB) load faster, but ultimately once the game starts it doesn't make much of a difference.
This is of course assuming you are buying from newegg.
