I am looking forward to add AM3+ board (and DDR3 RAM). This would be very helpful to get more friendly BIOS for my 1090T and after that I can overclock it slightly and adding a low TDP Piledriver in the near future. While looking at the detailed information about these boards, I came to know that the "black socket" 8xx chipsets are almost similar to the 9xx chipsets. Some features lacking in 8xx chipsets makes the main difference between 2. I want to buy the Asrock 870 Extreme3 R2.0 but if I spend more I can get the Asrock 970 Extreme3. I donít know what the major difference between those 2 mobos and I didnít see a single comparative review describing somewhere over there. The only difference I can see now is about the power gating. Is that it?
