Hi, i'm looking ram for my laptop, I see very nice price for this: http://www.amazon.com/Corsair-Vengeance-Performance-1600MHz-CMSX16GX3M2B1600C9/dp/B00EXPNG5Y There is something wrong with it? So what I need to do, wait for more price down, or buy? Maybe somebody can recommeend another set of ram?
