The reason i don't make alpha builds is that there may be changes (which might need workarounds) that will not make it into the final release. Once a version reaches beta, the feature set is finalized.
If you don't have an AMD GPU, you can try installing the Windows 7 Extended Kernel and run the official binaries. It says in the project's readme that Blender is supported, but i haven't tried it.
