You don't need that board. The 4 PCIe slots look attractive, but anything over 2 is not cost effective. Also, you won't be able to upgrade your RAM down the road, as it only takes one speed. I highly recommend the ASUS M4A79XTD EVO. It's cheaper and IMO one of the best values in AMD boards.
Gpu: I really don't wanna spend that much on the gpu. I know its come with directx11 and its newer technology but my friend has been using the 4890 and hasn't had any problems with it so i was thinking that was good for the price.
Mobo: Is nice and I was looking at it but what kinda pushed me to the msi is if i do sli both the cards can run at x16 instead of both running at x8.
