Thanks. Pretty decent and stable performance I'd say.

What about your post-processing settings?

Personally I think the 5850 would be a good choice. It can be nicely overclocked to near the levels of the 5870 on stock cooling, too.

SSOA is a post-processing effect disabled by putting post processing on "low" (I believe). The potential performance gain depends largely on the shader performance of your graphics card.

That's a good bundle - but such a system deserves a stronger graphics card. It's a bit of a waste of money spending £450 on an overclocked i5/mobo/RAM package if your graphics card isn't up to scratch. If you already have the 5770 and can't change your mind on that one, I'd see how the game runs but you'll probably have to play about with the settings a bit. Performance-wise the 5770 is worse than the last-gen 4870 in many cases.
