I need assistance choosing a DVI cable. My questions are:

1. I'm running at 1920x1200 @ 60hz, which is purported to be single-link DVI compatible. However, if my monitor is capable, I'd like to run at even higher refresh rates than 60 hz. Will blanking space cut into the 165 hz clock speed so much that a single-link DVI-D cable will be unable to provide me higher refresh rates?

2. Because 1920 x 1200 @ 60hz refresh is right at the limits of single-link DVI-D capabilities, will cord quality and/or other possible externalities cause picture degradation making a dual-link dvi-d cable purchase justifiable?

I just really want the BEST POSSIBLE picture quality my new monitor can provide me without buying unnecessary parts. Any information you can provide me will be greatly appreciated. Thank you for your time.

Additional information: My monitor looks like it's dual-link dvi-d capable, and I have twin 8800 gts video cards, which both appear to be dual-link dvi-d capable. My monitor can be viewed here: http://www.newegg.com/Product/Prod [...] Tpk=T260hd

Just get a dual link cable and be done, the most you are going to get is 75hz but it may not do that at it's native res where 60hz is more likely to be the max.

In all likelihood, the monitor will come with a single-link cable, and won't be able to run at higher than 60Hz at 1920x1200 anyways. Image quality is unlikely to change between cables, and it's probably not worth the money to change out the cable. I have a 24" 1920x1200 monitor, and I'm using the standard cable and the image looks fine.

The monitor's spec says that it can do 1920x1200 at 75hz, so it can do it. However, like you said, at 75hz it'll be right at the theoretical cusp of a single link connection (maybe even over it). I was calculating the numbers for mine, which is only 1920x1080, and it was right at the cusp at 75hz, so yours may be just over it.

I'd go with a dual link cable to be on the safe side.

Also, mycablemart.com has a VERY good explanation on DVI and HDMI cables, quality, and lengths.

Thank you Gentleman/(Ladies too if applicable) for your answers. I think the last reply was most applicable, however all your answers were prudent. I'm going to go ahead and get the dual-link cable, because like the last poster stated, my feeling is that my monitor's performance might push a little past the abilities of a single-link cable.

Thank you again for your prompt replies. The quality of people at Tom's Hardware is stellar.
