I wouldn't really worry about it for most games, though. Only games that are really CPU reliant might show less FPS than they could achieve with that card, but at 1080p, the most demanding graphical games will still be gpu bottlenecked and any games CPU bottlenecked are probably already over 60fps.
Still, OCing the CPU isn't that hard, you can get it up over 3ghz and see some overall system performance increase.
