I don't play that many games (all that I play right now is GTR and BF2) so my system is adequate (2.4 P4, 512MB RAM, Radeon 9700) enough to run the games at like 800x600. I don't really care so much about all the fancy stuff or running at 1600x1200 (although being able to run at 1280x1024 would be nice since that's the native of my LCD, but BF2 looks fine at 800x600), so no, I don't keep upgrading my computer. I got the system more or less as-is about 2 1/2 years ago and the only thing I'd remotely consider upgrading would be the video card, but what I've got works well enough for now. I'll probably try to squeeze another year at least out of it.
