I wouldn't recommend you that MOBO for a gaming setup. I bought the B85m-g r2.0 with a gtx970... and Ohh boy, I had random crashes all over the place, some games would work perfectly some others would be unplayable (semeangly random crashes out of nowhere). Some flash based application crashed all the time and what not...
At first I thought it was a problem with my ram, test were OK, prime95 run all night no problem, My supplier was kind enought to take my vid card back and give me a new one, Problems persisted.
At the end I bought a z97 maximus mobo from Asus... I have had ZERO problems since, system is rock solid now.
Maybe that MOBO is alright for a budget build, or maybe mine was defective.. Not sure at this point I don't care, rather save a bit more get a robust motherboard.
