Gigabyte X58A-OC Sub Zero Review
PC Mark Vantage
To quote the famous American statement, there is no replacement for displacement. The X58A-OC with a Hex Core i7 990X destroys our Quad Core i7-950 by such a large margin as to be almost beyond belief. It's not like the Core i7-950 is a slow chip, just that this setup is so amazing.
Once again you can compare your own system if you like.
