I think you might find most members won't recommend running win8 as your primary OS.

That being said I don't see why you couldn't install it since you need to do a fresh install of win7 anyway.

If you don't like it you can always go back to win7.

Also please take the time to fill in your system specs in your user cp.

It will help others help you in the future.
