Actually if you are trying to build a pc. Get the Phenom ii x4 965 and a HD 7770. The stronger GPU will help, and the 965 is actually stronger than the 6100 (especially if you overclock).
Also you get the benefit of having more upgradeable motherboard. You are also not controlled by the manufacture's "rules" that they put on it. Alot of pre-builts from Walmart, Bestbuy actually don't have room for a GPU at all. And ussually the PSU isn't good enough for a PSU. So building is what you want to do if your a gamer.
