And last but not least, consider the E6400, thats alot of money that you could put into gfx of mobo.
Bingo! Especially if you're gonna OC anyway. I'd think the 6600 was overkill. Spend the money you save there on the mobo. 975X instead of 965. Good ol' Tom's recomended the MSI 975X Platinum. Seems like a pretty good board for the price.
But then, I'm still a noob here, so take it for what ya will! :P
