I haven't seen anyone mention yet but this game isn't exactly a good example to go off of for performance. Maybe after v2.0, I don't know for sure, but the games engine right now is very unstable and not efficient as far as perfromance. Example, I am currently running a sandy bridge i7 overclocked at 4.5ghz on all 4 cores, 8gb 1866mhz ram with 2 geforce 580gtx cards in sli. @1920x1080, standard drawing quality with high textures, mouse curser on AO DoF off, I get anywhere from 30-60fps (60 outside, drops to 30 on occasion in a crowded area of uldah).
