Another look at NVIDIA Quad SLI

OVER THE PAST few years, we've seen an incredible number of extreme hardware solutions marketed to PC gamers: graphics cards that cost over five hundred bucks, thousand-dollar "Extreme Edition" CPUs, motherboards with more ports than Dubai, custom physics processors, and now even a "killer" NIC. Without a doubt, though, the most extreme of all of these offerings has to be Nvidia's vaunted Quad SLI. The concept of running four GPUs together for insane gaming goodness is more extreme than snowboarding down some wicked moguls into a vat of Mountain Dew at the X Games.
