2 Computers for the Price of one

[nedlands1]

Is it possible to divide up the resources on my computer and run two copies of XP similtaneously? I have a dual core processor, 2 GB of RAM, an 120 GB HD, an ASUS A8N-SLI Deluxe motherboard and a 7800 GT video card. If I was to buy a second video card, plug in another monitor, keyboard and mouse would it be possible to do this?
Thanks for your time in advance.

It's possible to do with Virtual Machine, but I wouldn't count on being able to output the other OS to another monitor, keyboard and mouse. VMware is usually used to emulate other OSes when you need to use another OS because of compatibility issues.

(IE: Emulating WinXP in Linux because some games refuse to run in Linux... even with Wine or Cedega)
