DL,
If you are looking to overclock your card get one with the fastest ram you can find. The faster the ram the more that you can push it before it locks. AsusTek also makes good stuff set up so you can accomplish this. Go to
www.pricewatch.com and you can find what you want for the least money. If you choose Asus, the "pure" versions have only a monitor out plug. the "Deluxe" versions usually come with a Video In, TV out, and a pair of 3d glasses to boot.
