I have no knowledge at all about these 64-bit processor's. My brother is upgrading his computer to one and before he does I figured I'd ask on here for some advice.

Windows XP 64-bit will be purchased to go along with the processor.

Other than that here I have some questions:

- Will all standard 32-bit apps still work?
- Will games like Warcraft 3, Starcraft, WoW still work?
- Is there anything else I should warn him of?
