Holy crap... i just installed the Aopen GeForce4 Ti4200 128mb card and wow! I'm now getting regular 60-80 fps. Wooot! I still need more ram as it's chugging on the hard drive every now and then... but damn, for $150 that was totally worth it. You should see Unreal 2003 in it too! And Quake cranked all the way up at 1280x1024. Nuts!
