64-bit XP is a horrible OS. If you want 64-bit, install the RC version of Windows 7 then buy it when it comes out. Or, if you're willing to suffer Vista temporarily, buy Vista 64-bit with the upgrade voucher and use Windows 7 when it is released. You can still use Bluray drives and upgrade your graphics card with a 32-bit OS. The only limitation is 4GB of memory in the system (including graphics memory).
The RC has been withdrawn as it is only 3 weeks from today that Microsoft release Windows 7 for full retail.
