i accidentally ordered a 280 and not a 280x... *facepalm* so i decided to just order the 280x anyways and return the 280 when it comes so i get both at the same time...however im also getting 2x amd pick 3 games gold coupon....would it effect my return if i kept them both? im assuming they wouldn't take the slip back anyways. This is thru newegg btw
