I was interested in this card but can not find any benchmarks. I currently have 2 xfx hd6870's in crossfire. I am wondering if I should get rid of my 6870's for one of these cards. I am running a single 23" monitor. I have 8gb ram and an amd 1055t oc to 3.8ghz. Also, would this run physix on games or would I need a dedicated card. Wondering mainly about running physix on arkham city and arkham city asylum. Thanks in advance.
