Haha good one! For playing old DOS games.May I ask what is the purpose for building such a powerful system? Cloud computing? Mining? SETI@Home?
VMs never work like the real thing. The main issue is timing - old stuff either runs too fast or completely out of whack. The only thing that works remotely well is PCem but that also has issues and bugs.You may use a virtual machine. A Pentium G CPU is enough for Windows XP
