Graphical Tests
Just to make sure the AGP implementation works, a few benchmarks that hit the graphics card too.
I remember the race to 10K with GeForce3 cards and Athlon XPs way under 2GHz. Seems so long ago.

The same kind of scaling that 3DMark 2001SE demonstrates, games tend to love fat on-chip caches and associated high speed and bandwidth memory subsystems.

UT2003 loves FX-51, stretching its legs and running off into the distance, again, for want of a better term.
Games performance is hot on FX-51, but you knew that already.
