What's your CPU and RAM? CPU power is important to this game.

CPU is i5 3.2 with 4GB RAM. Do you think I will see much of a difference between the 5770 and the 6970?

I've currently got a Vapour-X 5770 (playing with almost maxed out settings at 1920x1080) and I'm finding the frame rate is great provided I don't go into towns/cities. As soon as I do I get a large hit to frame rate and things start to become a little choppy.

I'm looking at potentially upgrading to a 6970 but it's going to cost me around $300.

Do you think I will see a significant difference? Is it worth the money or is there another card I should be looking at?
