I recently upgraded from a Phenom II 955BE (OCed @ 3.960GHz) to a FX-8350. I had been running Ubuntu and Mint on VB with the 955BE (Win 7x64) and it worked great with one or two cores used. I did a full clean install for the new computer of Win 7 (I don't like W8) but when I installed VB and Mint, it seamed much slower than it ran on the 955. Per core performance on the FX can be worse than the Phenom IIs for some tasks, but I have been reading that the FX CPUs are actually supposed to be great at virtualization.
Is there something I am doing wrong, do I need to select 3 or 4 cores to get good performance? I noticed a virtualization setting in the BIOS and I am not sure what it was set at when I first built the new comp. but I think it defaults to "enabled".

Re: AMD FX-8350 performance
I uninstalled VB when I had the poor performance. I will reinstall the latest version and try it again. Then I can give you that info.
