Nope, i have 3870 with Intel Core 2 Duo E6750 @ 3.0ghz and in raid Sunwell 25 man instance first boss Kalecgos, i have around 40 fps and lower. Also in Shatt with alot of ppl i have like 35 fps so you ca'nt ssay you max WoW with a slower card even with the 9800GTX or 8800GTS i had lower fps or about the same. So Im just wondering if Crossfire will make any difference cause some guy in my guild said he has 70 fps - 90 fps in raid like Hyjal / BT / Sunwell and he's running Amd Phenom 9500 @ 2.4ghz and HD3600 x4 Quad Crossfire
