My favorite PC game is Unreal Tournament (yes, the one from 1999) and I have a dedicated PC just for that. It has P4 3.2GHz, 1.5GB RAM, agp 7800GS GPU and CRT monitor (for the micro seconds response time). Maybe he has similar preferences.
Hey Funsurfer, you are my friend, well i played UT at 1999 and i made very good friends, i had some of the most fun gaming situations in this game, i will never forget it. However, just plug your crt monitor as 2nd on the better pc (if you have) and play UT there, you will love it ^^
