I have just recently bought another Gigabyte GeForce GTX 770 OC Edition 2GB card and have ran both my cards in SLI. I have tested a lot of games, and have seen that these cards achieve great frame rates but stutter a lot, these stutters make frame rates go from 120fps right down to 10-20 fps. The stutters/drops are most prominent in Battlefield 4, Crysis 3 and Assassins Creed 4, they are really annoying and are effecting game play majorly!
-AMD FX 8350 @4.00ghz

Desperate for a fix of some sort.
