Is there a way to bring the build price down a bit without losing quality? close to 800 would be good. I see the athlon II x4 640 as a good budget gamer CPU in a lot of builds. Am I getting a better deal with the phenom II x4 955 BE or should I get the 640?
I'd actually look at the X3 450 (or other X3 4xx) before the X4 6xx. The X3's are extremely low priced, yet offer great gaming performance.
Something else to consider, though it won't really lower the price (assuming that board is in a combo with the other CPUs), is the ASRock 870 Extreme3 as your board. It's the same price as the Gigabyte, yet has functional Crossfire speeds (8x/8x instead of 4x/4x). If you don't want Crossfire at all, the ASRock 770 Extreme3 is a great choice at $75.
Other than that, you're looking at lowering the GPU to either the GTX 460 (no SLI available period) or the 5770.
