A new CPU will not help if the BIOS and chipset do not support
virtualization. My laptop has a 64-bit AMD chip without virtualization,
and VirtualBox works fine. Without hardware virtualization, IMHO,
VirtualBox is probably the better solution. Our company uses VMWare
Workstation. VirtualBox does not support 64-bit guest OS's when hardware
virtualization is not enabled.
