You didn't incicate if you are running OSX or not so somewhat hard to answer.
If you do have OSX installed is Windows 8 x64 running under BootCamp?
Have you upgraded to OSX 10.8.3?
I installed Windows 8 x64 on a 13" MacBookPro i7 16GB back in December 2012 before OSX 10.8.3 was released: I then updated pursuant to this link.
Let us know your configuration in more detail and we shall try to help.
