Which processor should I get?

Hey guys, I'm planning on getting a new processor for me computer, I recently upgraded the graphics card for it from a on-board graphics card, obviously it made it run faster, but I have a very old processor, a AMD Athlon II x2 220, it's ok for minecraft, and I can play Skyrim at high graphics with it, but still, that processor sucks. So which is better? The AMD Phenom II x4 955 Black Edition or the AMD Phenom II x4 965 ?

Get the black edition if you feel like over clocking. Otherwise get the other one.

I've always used Intel i5 or i7.

Thanks for the feed back guys :)/>
