Turns out the GeForce 7800 GS OC isn't unequivocally the fastest AGP card around. It split the difference with the Radeon X800 XT Platinum Edition—and by proxy the X850 XT that runs at the same clock speeds—in our tests. The 7800 GS is probably the better choice overall because of its support for Shader Model 3.0 and 16-bit floating-point blending and filtering. These capabilities will no doubt make the 7800 GS more future-proof, as contradictory as that may sound for an AGP card. The 7800 GS OC also looks to be cheaper than the Radeon X850 XT, if street prices work out as NVIDIA has suggested they will. That pretty much makes the 7800 GS king of the AGP upgrade market—but if you cast off your Radeon X850 XT in favor of one of these, you need your head examined. The X850 XT may lack a few bullet-point features, but it's clearly the same class of graphics card.
