Phenom II X4 965 BE, $110 one newegg/tigerdirect, beats most fx processors, or an Intel Core i3 2120, is the same, little better than the 965 is $125 on newegg.
P2X4 965 is native 4 cores
i3 2120 is a dual core with hyperthreading making it a quad core
2100 i3 is a little cheaper than the 2120 and u dont lose much in performance, same with a 955 BE vs the 965.
