“Chicago (IL) – If even two graphics cards in your PC are not enough, what about four? SLI typically is limited to two cards within one system, but sources told Tom’s Hardware Guide that Gigabyte will soon offer a “Quad” motherboard with slots for up to four Nvidia-based SLI cards.”
This has been rumored for awhile, but now there’s even a picture of the motherboard! If you have a system with FOUR GPU’s, I can imagine you are going to need one heck of a cooling system. Check out the posting over at Toms Hardware.
