Yeah, the name is misleading, and sorry, i indeed fell for that.
Your board is in fact equipped for the task regarding the chipset.
I wonder if they ran out of 970A chipsets, and just built in available FX990 chips...
Still, as you already noticed, it has the same VRMs, and they are the problem very often (overheating, that is, and loosing their quality rather fast).
So, I'd still be wary about this board, for exactly the reason you mentioned.
There are just too many users complaining about 970A boards (with the same weaker VRMs) dying early when using 125W TDP CPUs (and today i'd not use anything less than a 8350 if i were to game with it), even with explicit gaming boards like the MSI 970A Krait SLI.
Rather not gamble on this, I'd say.
OTOH, I know, that getting an 990FX board for a decent price is already difficult... tough choice you have to make...
