You can't disable the 60 FPS soft limit in WoW, and there is no need to. A 4850 should be able to max everything, I have everything maxxed on my rig (sig), on 1920x1200, and I never drop to 20 FPS except when in the biggest city hubs, but nothing will save you from that. My friend with an i7@4.0 and a 295 drops in the new hubs too.....
