answer:I’m sure with many VM situations, I guess it all depends how much of your resources you give the virtual machine. For example if you have enough RAM to give it say 2 or 3 GB, then I’m sure win7 VM should run fine. (probably the same would go for graphics if you have a big enough card) I know I run XP VM if I have to, due to I can only usually allocate about 512MB of RAM and 10 GB of HD storage space on my machine.
