I've spent a ton of time researching who makes better RAM, and from what I gathered it's pretty much a "Push" when you compare "G.Skill" to "Corsair" Obviously Corsair's name brand makes it cost more. I'm going to go with G.Skill.
I've read so much about Gigabyte and Asus that my head is about to explode In the end I'm going with Asus. I've owned several MB in both brands, but ASUS has always been the better performer. Hope my 2 cents helps! Good luck!
