So my current rig is this : GTX 275, Phenom X4 955, 4GB Corsair 1333, OCZ Stealthstream 500W, GA-MA770t, and some crappy Raidmax case. I'm looking to get the 5870x2 when it comes out so what I'm upgrading will be the power supply and the case (I also want to get a good HS for the 955 since it's stock. Any recommendations?) I'm thinking of getting a Seasonic M12D 850W while it's still on sale at NCIX and a HAF 932. Any more suggestions of what to upgrade?
