i use GPU-Z and press Lookup and the browser opens its says HD7870
7870's the stated minimum. That's good. Minimum systems probably should outperform the consoles, but not by a lot.

Yep, I'm guessing that I will have to make quite a few compromises regarding the graphical setup, yet I hope that my rig would handle TW3 decently, since it meets the recommended specs.
I have the money for a GTX 980 but first I want to see how things will work out with my good old GTX770. I'd rather save that cash for a next gen card (talking about the generation which would come out sometime next year).
I think it will play well for you, and you can ignore members who post without knowledge making claims like it is barely above minimum. It just won't be up to the same eye candy as the 970.
