lol yeah i do partly agree with you realbenny....and ThatGuySmyth....it doesnt seem like its a hardware problem to me, seems to be some sort of a driver issue i would say...have you updated ALL of the drivers on your system?, here's a software that would help you identify what drivers are outdated www.reviversoft.com/driver-reviver unfortunately you have to pay for it to update the drivers for you, but once we know what, if any, drivers are out of date then we can update them manually from the manufacturer's website...also try turning down maybe something like AA settings, see if that makes a difference, also give V-sync (or adaptive v-sync) a try...that might help as well...also monitor your hardware temps while on idle and load, what power supply model do you have as well?....you mention 8gb of ram, i'm hoping thats not in single channel...also, your card has 2gb of vram, do you have fps drops while something massive is loading up on screen?, the card maybe running out of vram (although 2gb is not particularly easy to saturate), your system activity while playing games will also be helpful ..
this might be alot of stuff to go through but you know, thats what trouble shooting is
