But if you should believe in this yourself, why don´t you sell your quad qeon and go for a new honeymoon with your wife to a sunny place, can be a lot of fun!(this is not ironic but I guess you don´t fully believe in this, as you seems to be number one on your quad) At least I lost even faster against my AMD450 vs my P90 whatever program I use!
