don't take this the wrong way man but what did you expect with an old dual core and a 6570 low end gpu? You need to upgrade man, even an AMD apu would be an improvement. But I say either i3 haswell or fx 6300+7770 or 7790 and you'd be happy. You also need 8gb of ram total so you'll need 64bit windows.
what games exactly are you playing? That is a rather dated setup. Even a used cheap old sandy bridge i5 would be a major improvement even.
At the very very very least, get a core 2 quad and overclock it
