Lol, one simple word can describe a whole motherboard.
Who would need quad SLI? Any "gamer" out there that gets it is an idiot. If they wanna play every game max graphics they can wait a year and get a good video card and walla. Anyway, a 7800 GT is a great video card. A 7800 GTX 512 MB SLI is overkill. Still would be nice to have though.
