That's the best you will get cpu wise for that socket type, if you want to upgrade passed that point, you will need to spend $400+ on it to get a 980x extreme, which is the minimum I would do and still makes no sense. The problem is, I don't really know how much it will be bottlenecked, because there is no magic formula. I can say my phenom 2 x4 at 4ghz bottlenecked a 7950. Your cpu is a decently stronger than my old one, but not by a huge margin. Also, the 7970 is basically the same strength as a 680 according to most places. So I would go with that for gaming any day.
