Well what? I am not saying that you will face bottlenecks, because you probably won't. I'm just saying that running HD 6770 on that kind of system is very strange, like you have one Car and others were old bicycle. So to see boost the OP must upgrade anything else, PSU especially if it's below 24A on the 12V rail. I was not saying like what you said. And Gordon Freeman, don't insult people like 'Don't listen to these guys' because that ain't allowed in here and forum rules. Attack the idea, not the person, you could be nicer when you use 'The CPU was not going to bottleneck' without saying those words, rather than having those insulting word.
