Okay...but which one is made by the most reliable company and is a more solid choice in terms of quality and longevity?
Hands down ASRock. There is no question about it. In the past, i went with ASUS, but about a year ago, my asus maximus IV went bad, so i bought the ASRock Extreme4 mobo. Best. Decision. Ever.
Anyone i ever talked to about ASRock always swore by it, and now I see why. Ive had mine for a while, and I have no problems on my end. I suggest ASRock
