Thanks for clearing that up. As you say, multicore is the new norm. I have a
question as you seem knowledgeable. Do you get any benefit to running a 64 bit
processor with single core with a 32 bit OS? I had heard that you lose lots of
processing capability except it is of benefit when running VMs as they are able
to use the unused portion to run like a dual core.

I don't notice any benefit when running my AMD 64 on a 64 bit OS versus a 32 bit
one, but I have lots of RAM and a good video card and probably don't strain it
too much such as gamers do. I also don't notice any slow down when I run
VirtualBox with Windows XP inside Ubuntu 8.04 and therefore wondered about what
I had heard about VMs and 64 bit processors. Your thoughts might clear this up
for me.
