Gigabyte - eVGA
Core clock = 1020MHz, 1006MHz
Boost Clock = 1085MHz, 1072MHz
^GB has slightly better clocks than eVGA. Though much of a big deal really.
3 year warranty & AC4 free on both. Everything else is the same.
Though eVGA is known for its best partnership with Nvidia which doesn't mean much since gigabyte is also a solid manufacturer. I see Gigabtye is quite cheap in comparison so personally i would simply pick this one without any hesitation.
