Disclaimer: I have never done virtualization, so take everything I say
with a grain of salt.

I understand that some virtualization technologies don't require HW
support, but others do.  Since the OP stated that he wanted to do
virtualization, he should probably purchase a system with HW support,
to give himself the most flexibility, unless he's already certain which
technology he plans on using.

kvm requires CPU support. My understanding is that the performance of
qemu is much better when enhanced with kvm.  virtualbox can run without
HW support, but will / can utilize it if it's available.
