Just checking in here. I'm also having frame drops like crazy. 1055t at 3.3ghz with a gtx770. 8gb gskill ripjaw, win 7 blah blah. update on the 8th didn't really do much. Tried beta drivers and 2 previous versions. Still clinging at max 30 frames 17 on average, sometimes I'll get 7 during...
Personally I'd keep the 760 unless you plan on bitcoining. In my experience Nvidia is better with their drivers. I upgraded my 5870 to a gtx770 and couldn't be happier with the performance and software support. Unless the newer AMD cards have better driver support... Also not trying to turn this...
