just got one, was going to wait till the xp2000+ drop in price (it's standing @ around $73 @ pricewatch), but with still a $20 difference, I guess I wouldn't mind unlocking it and make it XP2000+.
Since i have a board with no multiplier and volt adjustments, I am going to hard mod it to a 12.5x multiplier. But I am not sure if I should mod the +0.1v also? I would rather keep it @ stock voltage but is worried if the XP1600+ agoia can handle XP2000+ speed @ stock voltage.
anyways, this is a good deal, after monitor the up and down prices (at least on newegg) of these XP1600, I doubt they can drop anymore. Thanks Corinthos.
