which motherboard is better for that processor

For sure it wasnt those boards . Gigabyte is not my favorite brand. Even if you get Asus mobo for 45 bucks , you ll encounter problems.

Lets compare : Asrock Z97 Extreme 3 and Gigabyte Z97X SLI - both $115 .
Both have SLI , but Asrock have 8 phase digi power desing ! But the Gigabyte simple 4 phase . its not good for overclocking at all
