What benefit will I see if I replace my single link cable with a dual link? I am currently using a GeForce 6200 and I will be using a Quadro FX 1700 on a 23 inch monitor.

Dual Link: Dual T.D.M.S. (transition minimized differential signaling) "links". DVI can have up to two TMDS links. Each link has three data channels for RGB information with a maximum bandwidth of 165 MHz, which is equal to 165 million pixels per second. Dual-link connections provide bandwidth for resolutions up to 2048 x 1536p.
Single Link: Single T.D.M.S. link. Each link has three data channels for RGB information with a maximum bandwidth of 165 MHz, which is equal to 165 million pixels per second. Bandwidth for a single-link connection supports resolutions of over 1920 x 1080 at 60 Hz (HDTV).
Dual link vs. Single Link: Don't believe the "hype" from some websites indicating that dual link cables are superior to single link cables. A single link cable is 100% as good as a dual link cable for single link equipment which covers about 99.5% of current equipment, including HDTVs, Projectors, Plasma Screens, and High Definition Set top Boxes. If your equipment does not specifically state it is Dual link in its specifications, it almost certainly is not. A better quality cable is a better quality cable, and single and dual link has nothing to do with quality. On the other hand, if both devices being connected support Dual links, then a dual link cable is the proper cable for the application, and you will have the capability of much greater resolutions and refresh rates. A properly designed Dual link cable should have no negative effects when used with single link equipment.

So yes? What resolution does your display support?

Hi, thanks for the quick reply.
I was just about to edit my post to add the resolution of my monitor which runs at the maximum 1920x1080. From what I have read so far the extra data pins give some extra rate but on this resolution it may not show and I rarely play games.
