Yeah, i heard that it will play current games on max, but... Borderlands lag like hell especially in DLCs. World of Warcraft lags in Dalaran and some places. But runs on 60 FPS in all smaller zones, dungeons, raids, etc.
sounds like you have vertical sync on? I get 120fps in uc all settings on ultra with patch 4.0.1 on a gts 450
