http://www.newegg.com That site is a good start. Careful with those cards though, ALOT of people have had issues with them since release, overall badass card though.
all great suggestions but i already have an 8800 gts and want to sli and newegg dont sell the 8800 gts with 320 mb of ram anymore.
If you want a deal, get the new radeon 4870 or 4850. The 4870 is the current best price for performance. Dont sli the 320mb gts, It doesnt have enough vram to proc well. I've had that setup before i upgraded to a 8800 gt and i've never been happier. Games run smoother with the gt vs. 320 gts. But in all seriousness, the 4870 is the way to go right now. If you dont want to drop the cash then get the 4850.
Alright. Someone has to tell him. SLI hype=Kimbo Slice hype. The 8800gt should be better than both those cards. Sell, save, and buy a better card.
I agree, SLI is overrated. I guess it depends on what you intend to do with it. Do you play FPS style games? Or games like WoW?
I'd say if you have the dough go with the new ATI cards, the benchmarks on em are looking pretty damn good looks like they are making a slight comeback. If I ever get the funds to build a new 'up to date' gaming rig I'm gonna give em a serious look.
