Ok, what about Planetside 2? Right now, I am jumping between the two games, I can barely get it to stay stable at 60 fps, would that be a GFX card problem or a CPU problem? Regardless, The difference in FPS seems negligible, 1.1 fps? Will the 660 give me as much trouble with temps as the 560?
Of course all games are going to show fluctuations in FPS. The best way to get the frames smoothed out is to lower a setting or two, then enable Adaptive VSync.
The 560 Ti was known to be a very cool card, but the 660 Ti should be even cooler. The problem with focusing so much on temperatures, however, is that the manufacturer targets a certain operating temp and sets a fan profile that maintains that temperature. Some target higher temps for quieter fan operation, and others target the opposite. So, it's not so much the temperature that should be a concern, but the rate of the fan necessary to maintain that temp. Anything below 75% fan on Auto with temps in the mid-80c's up to 90c is very normal. Lower is better, of course.
I suspect that everything in your rig is working as designed temperature-wise, so I wouldn't base that on a purchase/upgrade decision. In any event, make sure that your case and video card are cleaned out from excessive dust to rule that out of the heat equation.
By the way, Planetside 2 is a GPU-accelerated PhysX game, so you would need to upgrade to the GTX 660 Ti or another Nvidia card to continue to experience those effects.
Also, be sure to update to the latest Nvidia drivers as they include specific Planetside 2 enhancements.
