Im building my next machine but cant figure out what exactly to get. Heres my questions. Would you recommend the 680i or the 750i? I plan on running an 8800GT and my plan for upgrading the card later is to buy another 8800GT and run em SLI in about 2-3 years. OR. I could get the 750i which supports PCIE2 but I dont know what card to get. I noticed some 8800GTs say they are PCIE2 compatible even though the part description syas its only PCIE. Will it run on both buses then? I cant afford the new GTX series yet and I dont know if the 9600 series is any good compared to the 8800GT. Also, how big a power supply would you suggest with SLI 8800 or 9600. Iknow a 600 would be fine for one but would it push two? I do not plan on overclocking AT ALL by the way so scratch that option if one mobo or the other is better at it. Im set on a proc, Q6600, I plan on doing video editing as well as gaming (FPS for the most part, Crysis, COD4 and the like) so I want quad.
