Thanks for the quick reply's guys. I'll be get a 460 sc not the se and since its cheaper than the 6850 I'd rather go with that. If the 6850 only requires one 6 pin than thats the better choice for me because I'm cheap and don't want to pay extra to get a 4x6 pin power supply to sli 460's.
How about this power supply -->
Apevia ATX-WA750W Warlock 750-Watt ATX Power Supply - SLI and Crossfire Ready, 135mm Fan, Clear Sides at TigerDirect.com
The motherboard I'm getting only has one pci express x16 slot and its $50.
Altogether I'll have to pay $40 for the upgrade to 750 watts and $50 more for the better mobo = $90
:( Is it really worth all that extra cash for sli? From your previous builds and experiences would it be a better idea to spend extra, cause I'm a college student just trying to get the best bang for the buck to play Crysis 2, Skyrim, etc, etc.
