Those who wants to know more about NVIDIA's Quad SLI technology now that it is available in retail form and not just to those who bought high-end systems from PC builders they have over at HardOCP published an interview with NVIDIA where they discuss several interesting questions.
"The sweet spot for Quad SLI on today’s hottest games (F.E.A.R, Quake 4, Prey, Battlefield 2, Far Cry, Doom 3, Half-Life 2 Lost Coast, etc.) is 2560x1600 with SLI8x antialiasing and 16x anisotropic filtering. At this setting, you will see from 30% to 80%+ gains compared to dual GeForce 7900 GTX graphics cards."
