for a physical machine like this:
Intel Core i7-740QM 1.73 GHz / 1333 MHz, 6 MB L2
512MB Nvidia Quadro NVS 3100M
Win 7 Pro 64-bit
what is the better choice - VMWare Player, or Windows 7 virtual PC?
Guest OS's will be mainly XP sp3 pro 32-bit.
Better choice means mainly better guest performance. And, less impact on the host OS, when a VM is not running / VM is started but minimized.
I found lots of comparisons, but outdated.
