Honestly for $100 you can get a FX-4100. It may perform slightly less than 965 (in windows 7) but it does overclock to 4.6 if you desire. Win7 doesn't work efficiently with BD's architecture so we should see a 15-20% improvement in Win8 or possibly a new Win7 service pack.
You can also get a AM3+ motherboard starting at $55. Throw in 8GB of DDR3-1600 and you got your self a AM3+ quad core ,mobo and 8gb ram for $175-185. Unless your running 2 or more high end video cards, it's going to perform just as well as other more expensive cpu's.
