I have this video card since August I played every game at ultra settings. my temp is 43 to 56. Now ive just install the newest driver from nvidia the 327.23 then now all my game LAGS! . I have 115+ FPS in dota2 now it just 20+ see the difference. In battlefield 3 i can play it in ultra settings with no lag now it lags in every corner i shoot . And then this is the funny problem i play gta SA very smooth (even no videocard) but why it lags in GTX 650 TI Boost. Any solutions, ( idont have any fans in my computer) specs:16GB Corsair, Intel i7 3770k, GTX 650 Ti boost, MSI b75a-g43, SSD 150Gb, WD 1TB
