I need this please
Nearly any 970 board that is made by Gigabyte, ASUS, or ASRock.
What's your budget?
If you post your entire build we could look it over for you.
as nice as you can afford, depending on what you plan to do with it and how. If you want to overclock an unlocked one with the multiplier, then you want as many power phases that you can get. In this case, the ASRock Extreme9 990FX is the cheapest motherboard with the best power phase control, but it seems like a bit of overkill for that chip. If you feel like using the difference in native bus speeds and just overclocking primarily with raising the bus rate, then you should be okay with most 970 powered boards. I like the looks of the MSI 970A-G46 as it has the same number of power phases as just about every single other 970 powered board, and it has their military grade components and SLI/Crossfire support and full 2133 MHz RAM after fixing the native speed of the memory controller in the processor.
Basically, you get severe overkill, or you get nicely specced mediocrity, so it really depends on what you feel that you NEED.
