Our testing with 3DMark05 and Doom 3 was rigorous but it wasn't extensive, as we could have easily selected six different games, and we would have very likely found that one particular graphics chip had an advantage in your preferred game.

Then the manufacturers would release a new driver version, various games would be patched and updated and we'd have been back to square one.

Accepting this, we bit the bullet and built a test PC with a 3.4GHz Pentium 4 Extreme Edition CPU on an Intel D925XCV motherboard with 925X chipset, 1GB of DDR2 533MHz memory and a WD740 Raptor hard drive, and then ran the latest version of 3DMark05 and Doom 3 at two different resolutions, both with and without FSAA and AF enabled.
