Yes, you're now into unsupported hardware land, unfortunately. Even if you were to install it on a system that DID have NX support built in, image it, and move it over to a system without, the OS checks certain things on boot and will bugcheck 0x5D as soon as it finds a CPU that doesn't meet the minimum requirements. I suppose (if you knew where that check was) that you could try to fool it, but ultimately Windows 8 RTM *requires* NX (not only for DEP, but some of the appcontainer sandboxing and the like), and if your system's CPU doesn't have it, you shouldn't try to run Windows 8 on that machine. Stick to Windows 7 or something else that doesn't require newer hardware, and you should find the hardware continues to serve you.
