Which motherboard would be best for an AMD Phenom II 1090T black edition?
The guys are right. Lots of great motherboards out there for it. But finding the best one for your need will require a little more info on how you intend to use it plus any components you already have or plan to use.
For example, if you don't game than a board with integrated graphic would be a consideration. What size case? Anything you have already settled on would be helpfull.
