Madshrimps stumbled upon an enthusiast forum posts, he got his hands on a 7800GS for AGP and he compared it to his X850XT AGP card in a
series of benchmarks, including 3dMark, Doom, FarCry, Fear, Half Life 2 and others
His findings: "From these benchmarks, the GeForce 7800 GS at stock speeds performs close to a Radeon X850 XT, usually being slightly
faster in some tests, and slightly slower in others. It is only when the 7800 GS is overclocked where the performance is a bit
better than the X850 XT"
