Well 1st Alienware. Well i can pay weekly so i can afford it. Well i don't have my Alienware yet but its maximum it can OC is to 3.2Ghz on a i7-920. I don't have it yet. But i heard people try to overclock it higher but it becomes unstable. is it possible to change the Cooler or is it because of the motherboard. The Cooler is the Alienware Extreme Liquid Cooling (like a H50 with an alienware logo)
