If the Upgrade Assistant complains about NX, see whether you can turn it on in the BIOS setup.
A very nice follow-up post with sound concerns and recommendations! I have attached an official Microsoft document that expands on the PAE, NX, and SSE2 requirements; however, since multiple posters have successfully installed Windows 8 (without NX support) then maybe it is no longer a solid requirement but I'm guessing that some Win 8 security features might be unavailable. Anyway... Cheers!
