I used to use my ATI 9250 PCI 256 card and got..
Resolution : 1240x768
Details : Low
Anti-aliasing : Off
FPS : Not sure, never tested
Draw Distance was at full.
I now use my new (and I know its a old card) FX5200 256 PCI and it gives me better performance in OpenGL games. I haven't tested this card out yet on GTA, but soon hopefully I will I hope its better then with my ATI.
@Watti, I would send you this 9250 if I could and if you payed me $40 american dollars.. I payed $80 for it.
Games I play on this card are... Skulltag (source port for Doom), Halo, Counter Strike 1.6, Day Of Dayfeat, The Specialist, Wolf:ET, Quake 2, Half Life, and soon again GTA SA... I am just waiting to get my PSP, so I can share this PC.
