I am currently using MS Virtual PC 2004 on a Windows XP Pro system. I
use it to run a second instance of XP for experimentation, to avoid the
risk of messing up my main system. The host computer has 4GB of RAM, and
I have allocated 1GB of RAM to the virtual XP.

I have downloaded both MS Virtual PC 2007 SP1 and MS Virtual Server 2005
R2 SP1, but I have yet to try either of them. How should I expect them
to perform relative to MS Virtual PC 2004? I am interested in obtaining
better CPU usage efficiency if possible, but I'm wondering if these
newer applications will actually put more of a load on my CPU, an Intel
820 Dual Core P4.

Do either of these newer apps have additional features that I might find
worthwhile? Vista compatibility is not currently a concern. Thanks!

John
