Quake 3 Arena
Quake 3 Arena was always Pentium 4's big strength. Pentium 4 2 GHz can score an impressive lead over Athlon 1400 at the low resolution, while the high resolution is limited by the performance of the graphics card, making all CPUs perform almost alike.
Under Windows 2000 the picture ain't much different, but Pentium 4 is able to score a slightly bigger lead.
