New gaming system 4850x2/4870x2

Hello. So i've put together a list of components for a new gaming pc, actually I've already ordered it and I'm having regrets . I just took a look at the mid range build from november, and my system is very similiar. I am satisfied with my cpu choice, but I am considering sending back the 4850x2, and upgrading to a 4870x2 I'm just not sure if it's worth the extra 200$ and the effort of sending it back, so what do you guys think? Below are the rest of my specs, any criticism or changes I should make?

4870x2 is overpriced for today's games. For tomorrow's games, buy tomorrow's value cards and save money all week.
