So I built my new gaming rig 2 weeks ago, once I was done everything was working fine but then my mouse cursor started to 'lag' on screen and when I opened any application even a blank page on chrome my PC started to slow down till it would just crash.
I tried a ton of things to solve this and finally found it was a problem with the GPU (worked fine with onboard and old GPU) so I sent it for RMA.

The company I bought it from sent it back saying nothing was wrong with it so I have tried different drivers and settings but nothing seems to have work so far.
(Tried Nvidia 320.49, 320.18, 314.22 and 314.07 plus the one that comes on the disc with the GPU)

I am currently running the 314.07 and it seems to have HELP'ed but I still cant run games and even videos start to get 'laggy' after 5 minutes or so.

To define the problem more, in games for example battlefield 3 it will start out (on LOW settings) 110-130FPS and feel as if it is on 30FPS (mouse feels laggy and the garphics look like a slideshow) then it will start getting worse and start jumping between 40-60FPS which for my system specs is stupidly low. And my old AMD 6870 card scores 7.8 on graphics in windows index but my GTX680 which the meant to be a lot better card scores 7.5 for graphics.

VSync is OFF in games and the nvidia control panel and system is set to performance and my PC stays between 40-60 °C and the GTX680 under load is between 45-70 °C so I am sure it is not a heating issue.

Any help is very appreciated seeing as I spent a lot on this rig only for it to be held back by one issue that for what ever reason I can't find a solution for.

Also found this for Battlefield 3 benchmarks for a GTX680: http://www.tomshardware.com/reviews/geforce-gtx-680-review-benchmark,3161-8.html
and seeing the FPS they got on ultra settings and the fact I cant get that stable or at all on the lowest settings means something is wrong?

I hate to say it but it really does sound like a driver issue. Take the nvidia card out, reboot using the onboard, and totally uninstall the old drivers and completely remove them from the system (including any downloaded drivers, literally get the files off the system because if there are corrupt drivers, windows will find them and autoinstall them). Then restart the system and let windows update install the universal drivers or Windows' last known good drivers for that card. See if the problem is still there.

I have noticed that any OC'ing I do to my CPU the GPU starts to slow down and do all the problems listed above.
Has anyone heard of anything like that?
Where they GPU is under clocking itself because of an OC CPU?
