You could make a 990 board with 2-phase power if you wanted to, but no one in their right mind would use it. It's entirely a decision of the motherboard manufacturer as to how they configure the VRM's on their boards.

There's more to this than power phases, anyway. The VRM's on a Biostar T-series board (TA970XE or TA990FXE) are very high-quality and are properly cooled. Both of those board are excellent overclocking boards, and marketed by Biostar as such. There are some 8+2 boards out there that don't deliver power or overclock as well as a TA990FXE. Biostar just takes a "quality over quantity" approach to the VRM's on their enthusiast-level products, and it seems to work for them.

The Gigabyte board you mentioned is notable as the only 8+2 board that uses a 970 chipset, and uses good VRM's. For that reason, it should be a top choice for anyone looking at a 970 board.

There is no difference at all in the quality of a 970 chipset vs. the 990. The only difference is that the 970 is limited to one x16 and one x4 PCIe lane, so using Crossfire causes a performance hit. But, as already mentioned, most 970 boards are not built by OEM's with enthusiast-level components, and for that reason only, don't perform as well as 990 boards.

I'm going to back up this comment and show you what is talking about Biostar TA990FXE mobo.
Here is a Biostar TA990FXE (4+1) with a FX-8320.


EDIT
And Add this comment too.
In most cases a 4+1/4+2 mobo is not a good idea for a high oc on most to all Phenom IIx4/x6 and FX- 6***/8***.
6+2 is for a mild to medium oc.
8+1/8+2/12+2(which are double 6+1) are for high oc.

I don't think biostar's board is bad, infact i just recommended it in a thread you were in. I was simply correcting the first person to respond on telling that that a chipset and vrm have nothing to do with eachother and choose too boards on the furthest ends of the spectrum i could think of off the top of my head. I know very well that Biostar's 990fx board is the best price/performance board you can get and has GREAT overclock potential.

Just to be crystal clear, i am not gauging at the quality of anyone's vrm's here, i am simply stating that high quality chipset≠high phase vrm.

Well I was just backing Cannon19932006 on the quality over quantity comment and showing what he was talking about. That is it sir.
