I had a minimum of 55+ in caspian maxed out with 4-8xAA and High Post AA. Too bad I sold those however. Now I'm going to be stuck trading my Dual GTX 560 TIs for 2 x 470s and OCing them for the extra Vram, and possibly adding a 3rd to hold me off until the 6xx series and 7xxx AMD series matures a bit.
You realize that crossfire *and SLI requires a game specific profile/driver right? xfire was never enabled in BF3 beta. So only a single GPU was utilized. I'm shocked that you weren't aware of games requiring profiles to enable crossfire / SLI. AMD is actually providing more timely driver/profile updates to enable dual GPU in newer games compared to nvidia.
Also, 6970 crossfire is faster than 580 sli because xfire scales better than sli. Me? I've got a crossfire 6970 rig along with a 580 rig, and its ridiculously fast - but ii'm going to stick to single gpu from now on until a more elegant smart vsync is developed. Microstuttering is pretty annoying to me.Edited by xoleras - 10/20/11 at 5:50am
