XP 64 Bit

[The Mad Rapper]

What issues, if any, would I have using 64 Bit XP on my new AMD Phenom II X4 system? It has 4GB RAM and will be used for gaming mainly. I finished building it yesterday and it's presently running a Windows 7 Beta, but I'm not sure how I feel about it.

Thanks. The only game I'll be playing is Dark Age of Camelot - not sure if it's happy with a 64 Bit OS or not, although it runs nicely on Windows 7 32 Bit.
