Eh, I'm a pretty big computer gamer, but lately I've been busy with MLB 2k6 and GT4. As for computers, the main games I play would be CS, EQ1/2, Madden 2k5 (online play rocks), Battlefield Vietnam sometimes, Rome: Total War, and IHRA.. I've got a bunch more games, but those are the main games I play. As for my computer... it's a bit outdated, but oh well..

Dell Dimension 8200
p4 2ghz
1 gig of RamBUS (god knows why Dell made me buy the expensive gold plated bling bling ram...)
330gb (plenty of movies/games/mp3's...)
21" Nokia big fat ass monitor (thanks to Atif)
ATI Radeon 9800 pro 128mb
and ughhh guess thats it.
