I already own a 710 and it works great. But my wifes cpu just messed up and I was thinking of giving her that one and get me a 720 with a good heatsink. She only plays games like sims 3 not really hardcore games. She only has a 1950pro. Will it be a big differece if a got me the 720 and overlock it higher? I have the 710 around 3.3ghz. But looking at the way my wife plays should I get her a athlon II for around 60$ and save my money.
