I am considering buying an AM3+ GIGABYTE 970 ATX motherboard from here -> http://www.newegg.com/Product/Product.aspx?Item=N82E16813128602 <-. Is this a good quality board? My friend said he has had GIGABYTE boards break on him in the past, but all the internet reviews are positive. Is this board good enough to support an AMD FX6300 with mild overclocks? As well, I notice that this boards PCIe 16x are running at 16x and 4x. Will CrossFire work with two Sapphire Radeon r7 265's?
