The threads title says it all. I currently have a BFG 9600GT and want to upgrade. I could get another 9600GT to run in SLI for $80 or get a 260GTX for $180. I have looked at benchmarks but ultimatley is the extra $100 worth the fps increase ? I have never run a SLI system and understand it can be a hassle though. Then again if i did go with the 260 i could run the 9600 as a dedicated physics card. Does anyone have a similiar experience or system ? Any suggestions ?
