I'm considering to upgrade my GTX 295 to a 680, it may very well be time. Before I do, I have a couple of questions regarding if my system will be a bottleneck. I have a good set-up, but some parts are a few years old.
i7 960 @ 3.20 GHz
12 gigs RAM DDR3
850 W PSU
MSI X58 Pro-E (MS-7522)
I imagine I'm good, but I'm most worried about my PSU and mobo...
Also, another question: My GTX 295 right now runs pretty hot (around 65 C when gaming...), and my system temps are a little higher than I would like, however not high enough to warrant installing new cooling solutions. Would upgrading to a 680 require some better cooling? I don't know how hot it runs in comparison to my 295...
You should try to overclock that cpu and you will be fine,as for the PSU if it can power a gtx 295 it can power a gtx 680.
