This compy runs most games well.

AMD Athlon XP 2500+, Stock Cooling
Soyo KT600 Dragon Plus
512 MB PC2700 DDR RAM
Seagate 40 GB
Maxtor 200 GB
Powercolor ATi Radeon 9800 256 MB DDR RAM
Using built in 10/100 ethernet adapter
An old D-Link 10/100, I have it in here because some versions of Linux don't like my built in ethernet adapter.
Windows 2000 Professional

As I said, it is a decent computer, runs all the games I like. Wish I could just get an AMD Athlon 64 FX-55 with two PCIE x16 6800 Ultras. *dreams on*
