If you take a good look at this Gigabyte X800 Pro Review at Motherboards.org, you'll see the kind of graphics card that might just switch me from being an nVidiot for good! Sounds like some brutal performance:
"If you're looking for an AGP card today, there is little doubt in my mind that the X800 Pro card is the card of choice. Its performance in the games I play today is simply amazing. Many times I did a double take at the performance of the X800 Pro. Turning on 6x AA and 16x AF in games does not cause the games I've tried to go to unplayable levels even at 1280x1024 32 bit color."
Quite an evil graphics card, here.
