I posted a similar question but got no answers lolIs there any reason the extreme amp trumps the gaming x apart from out the box clock speeds? Think I'm going for the gaming x as have always preferred msi as a supplier. Had 290x in crossfire and currently 980ti in sli, all msi but time to give up the dual card game as it seems to be a dying art.
Very pleased with my card though and runs 2050Mhz all day long with no issues at all
