SLI is looking pretty damn nice, ive seen information that says it can increase perfomance a solid 80% over one card of the same kind. is this the entire future of gaming? will gaming companies begin to sell all videocards in 2x packs? anyone know any prices on this stuff yet? and how much sense do you guys think it would make to go for this before it becomes mainstream? i saw the first system built with it in a pc magazine i got this month. it was 3000$ when configured with 1 gig of ram, 2 Nvidia 6800's, athlon FX55 a damn fine case, flat panel monitor, speakers and everything else you need... how much to configure a system like this?
