Ok Im planning on getting the Asus X1900XT 256MB thats HDCP compatible and Im gona overclock it. I was just wondering which heatsink would be better, a stock lapped one or the vf900? I like the stock one cause it acts as an exhaust but does the vf900 really decrease the temps that much also I know that these cards dont OC that much anyways so would getting the vf900 be worth it?
