You're gonna get basically the same answer I gave you in the other thread from almost anyone else here, lol (unless they're fanboy's, lol).
Disregard the 6100, and go with the 965 or 2120.
Like I also said in the other thread, the 2120 would be better for gaming than a stock speed 965, but an OC to the 965 will even it up.
Honestly, out of the 3, I'd go with the 965 (because it's a quad core and in games like BF3, that's beneficial). The 6100 is a faux "6 core" with 6 integer cores, but only 3 execution units. That, combined with the slow architecture, makes it not worth considering.
