So I have an oldish Core 2 Quad and a new GTX 560 Ti that's been OC'd. The particular Core 2 Quad I have is the Q8300 and my GTX 560 Ti has 944Mhz Core Clock, 1888Mhz Shader Clock, and 2200Mhz memory clock. I've been running at high but other people with GTX 560 Ti's claim that they can run at Ultra with no problems! Is my CPU the bottleneck or is the GTX 560 Ti just not that powerful?
Thanks. (I ask too many questions....)
Edit: oops I forgot to say the game I'm talking about is Skyrim :P
It really depends on your tolerance for low frame rates. Some people want all the eye candy and are prepared to endure significant variations in frame rate, whilst other need frame rates to be more consistent.
I have a pair of 560 Tis in SLI and can tell you for certain that I would certainly not run Skyrim in ultra at 1080p if I had a single one. Those who do will get a choppy experience in the cities.
So with a single 560 Ti, I'd say go for high, not ultra, and be prepared to drop the AA down a notch.
There's one other thing. Skyrim is a more CPU limited game than most. This means with a relatively old C2Q, some of the choppiness will be due to your CPU. To test this, try dropping the resolution. If the framerate is still choppy, the CPU is bottlenecking your system. If not, it's your 560Ti. If your CPU is the problem, then the good news is that you can increase the eye-candy/resolution without penalty. The bad news is that there's little you can do about it except upgrade your CPU!
