Hi I recently got hold of a 7950 to replace my gtx460 however I am struggling with a rather annoying issue. V-sync seems broken, I have it set in my games no problem it does go to 60fps however taking one game (it happens in EVERY GAME) League of Legends, easy performance on my gtx460 and always stayed at 60(give or take 2fps), the 7950 seems to get to 60fps and stays there for a bit but when I scroll around the screen or anything happens it will intermittently go down anywhere to 45FPS and take a second or two to get back to 60. The card is only running at like 50% as its an extremely easy game to run it doesnt even clock up much at all ( it goes to 500mhz core) it just seems odd that it cant hold 60fps. All my games feel off because of this, starcraft used to be fluid but I cant even maintain that 60fps (its slightly worse). Borderlands 2 also seems to be quite dire in performance, I was OK on my 460 but on this 7950 I go indoors and drop from 60fps to 15/20fps relatively quickly and it takes an age to get back up, however the gpu usage goes down to <60% when the FPS drops.
Any suggestions? I havent used an amd card since my 4850 which worked fine so I am unsure if there are any tweeks I need to make. I have tried catalyst 13.3 and 13.2 drivers, will be trying older ones tonight when I get chance though.

. I did remove the Nvidia drivers by booting into save mode uninstalling everything and using driver sweeper to make sure. I will try that method again see if it improves if not I will just quickly run a fresh windows on it.
