7/10.

A Phenom II x6 is not really worth it when it comes to games.

You should have spent that money on an i5 2500k or waited for AMD's new CPUs to come out.

850w power supply is over kill, you would have been fine with a 500w PSU.

The case is alright but you may want to purchase some dust filters.

8 gigs is overkill right now unless you are doing some serious rendering work.
I would have gone with 6 gigs in triple channel using an i5 2500k.
