Yes, WindowsNT graphics support is crap. Also AGP graphics is poor. I run GP3 and 4 on winxp and never have problems with hotlap replays. Your RAM should be ok. The TNT is not the best of cards and in performs really poorly under any WinNT kernel (ie. winnt, win2000, winxp) but runs well on win98. Geforce 4 MX's are really cheap to buy

I personally would upgrade the graphics but ram is also cheap aswell for 256MB and you would see improvements.
