While my 4890 is being RMA'ed, I can't play GTA IV. I've got a Geforce 7100GS 128MB that I've overclocked from 350/666Mhz to 475/1000Mhz. I can't play GTA IV on it. I was thinking of buying the GTA Trilogy (III, Vice City, San Andreas) for $20 in the mean time. Can the 7100GS play any of those three games?
