Quake III Arena
The Athlon XP 3200+ makes a nice showing in Quake III, but the Pentium 4 has long considered this test its home turf. The move from a 333MHz bus to 400MHz is good for nearly 10 frames per second in our Quake III test, for what it's worth.
3DMark03
3DMark03's CPU tests show a real advantage for the Athlon XP 3200+ over the 3000+, but the clear winner here is the P4 3.0GHz/875P chipset combo.
Serious Sam SE
If the P4 considers Quake III its home turf, Serious Sam SE is the Athlon XP's home field. However, the gap between the top three contenders here, including that pesky P4 3.0GHz, is only about four frames per second.
