So I have a pretty beefy system but I play on a 30" monitor at 2650x1600 and
cannot run everything on Ultra at anywhere near a good framerate. I run the game ok (50-60fps) on High setting but it makes the fan in my GTX Titan sound like a jet engine.
So yeah, graphically this is a pretty demanding game. But, I suspect some of it is bad optimization that will be fixed soon.
Still most people dont play a that high a screen resolution. I suspect at 1920x1080 I could easily run it on ultra. I would imagine you could maybe run it on low or medium but check the min specs before you buy. They are pretty high.

It looks like you are just below "recommended" but well above minimum. There are a lot of setting you can turn down though to make the game run smooth. There is a slider you can use to set the "resolution quality" (not even sure what that means) that can help you tweak the game to your system.
