Mac OS Virtual Box performances If you run Mac OS 10.8 with Virtual Box (on Linux), on a computer that supports hardware virtualization, how good will be the performances?

With a powerful computer (i7, 8gb of ram, ssd hd), would you be able to run music softwares like Ableton Live, Traktor, etc...?
yes performance is excellent with hardware virtualisation. Ableton, pro tools, cubase all run great on i5.
