Settle down Francis. I'm in no way saying GSkill is bad. (In fact, the only reason I didn't get your same HZs for my build is that the Ballistix were half the price at the time!)
The OP indicated he would be doing "some" OCing. And I'm simply pointing him out the complete listing of 2 x 2s when you showed him only GSkill. For his purposes, I'm betting the Corsair or the Mushkin set would also be good choices for about the same money. And I can personally vouch for the customer service of Corsair, Mushkin, and Crucial too because I've owned them. His call either way.
Crucial does not make 2 x 2s but even if they did, you wouldn't see me only recommending that brand -- that I'd guarantee. I am not wedded to any brand of anything.
