I used the Expert 2000 in my son's system. PIII 550@733, p3v4x, 256mb... It's not to bad. Although you may not be able to play quake3 at highest resolutions with acceptable framerates, it will play decently at 800x600. We also play NFS/PU, Motorcross2, NascarHeat, Combat Flight Sim2, Unreal Tournament and others. Well pleased for the $45 spent. If you do much gaming at all, go for a Radeon LE.
