Actually it's CMT, not HT. Windows 7 doesn't even know how to address the FX cpus at all. Even with the Windows patch, it treats it as HT which still does not utilize them to their full potential. FX-4100 is a true quad core in the sense that there are 4 logical (physical) integer cores. The reason the 965 performs better is again due to Windows. Windows 8 is supposedly better, though how much I'm not sure. Put both on Linux and watch the 4100 leave the 965 in the dust. The FX series are simply ahead of their time. That said, if the OP is running mainly single threaded apps then I would recommend a Phenom II X4. If running mainly multi threaded apps, then go with FX-8120.
