The Amd's do fine in virtualization. They support both AMD-V and IOMMU. They are not as powerful, per core, as an phenomII or thuban though so If you were thinking of picking up an FX 4 series get a PII or Thuban instead. The FX8 series is about equeal to a thuban x6
I already own the FX-8150 and after gigabyte put out some bios updates I really have no complaints. Overclocking seems to raise its processing power exponentially. I was only curious about virtualizing
because of it suppose to excel at mutli threading operations. So I was just curious if it would out perform in a heavy virtual enivroment.
so far I've had a total of 4 VMs running, 2 x64 OS and 2 x86 OS and it hardly put a dent in the resources.
