What motherboard would fit AMD Phenom II + Sapph Radeon 6850?

Any AM3 socket motherboard. I will though suggest AMD 8xx chipset series board to get the newest technology. There are different features to be selected on the different boards but here is one that is a good buy at the moment http://www.newegg.com/Product/Product.aspx?Item=N82E168...
If you have not bought that PSU yet then I suggest swapping it for a similar size Antec, Corsair or Seasonic!

What about this Motherboard-if i want to have open options for upgrading?

- GIGABYTE GA-890FXA-UD5 AM3 AMD 890FX SATA 6Gb/s USB 3.0 ATX AMD Motherboard

It is a top of the line AM3 board and an excellent choice!

What is everyones opinion on the Asus Crosshair IV Formula and the MSI in the same price range? I forget the name of the msi >.>

I SECOND THAT: Too many people under estimate the importance of a strong, quality power supply. Choose one from Corsair, Antec TP, or Seasonic...

650watts will work for any SINGLE GPU system.
850Watts will work for all but the highest end DUAL GPU systems.

This motherboard for Nvidia, supports SLI in the future.....

I heard it is withdrawn from the market due to some bug being discovered.
It is going to be re-introduced within month or two though.

With that exact same processor and ram i used the following motherboard and PSU in my rig

Of course the MOBO is out of stock ATM but I am happy with those purchases, and am running dual 5770's in crossfire without issues with these items
This motherboard is pretty much exactly the same as the other I posted

This was my first AsRock mobo purchase and I am happy with it. Zero issues whatsoever. Hope that helps

Any mother board with an AM3 socket. I would recommend looking into one with USB 3.0 and SATA 6.0 gigabytes a second.
