need help building up pc collection

after upgrading my rig will be a celeron D 3.2ghz,1gig of ram and a 7600gs or gt and of course i know it won't play newer games but i was just looking to play some older good games from like 2003-2005 untill i build a computer later next year so i was wondering what are some good games in that time frame

Um, your PC is decent. I have almost the same rig, with a bit worse video card and a better processor, and I play things like Battlefield 2 on full settings and Oblivion on medium settings.

DOwnload some demos, see what runs well.
