i need a gpu that can run gta 4 and nfs maxxed out, but i want a dual monitor setup also. I want to play gta on 1 and use windows on both. these are the only two series that i play and dont have anymore heavy video applications, but i heard that gta 4 has bad coding and requires 512mb for max but i want a dual setup (most likely 22'z)so im stuck...
