Hi, I got two 8800gts (only one in right now) and a Samsung Syncmaster 931BW for my gaming rig. Btw, the lcd screen is 19" widescreen, 2000:1 contrast ratio, and 2ms response time. I was wondering, with the current set up, is there going to be a noticable difference between using the dvi connection rather than the vga? If there wont be a difference to me, what difference will there be to my computer?

DVI is better than VGA for TFTs because they are digital and VGA is analog. A TFT displayes its picture digitally, pixel per pixel. Via DVI the panel gets data for each pixel, so the picture generated in the graphics card will match exact with the pixels on the panel itself.
Not so with VGA. First, the picture is generated digitally in the graphics card. Then it's converted to analog. In the TFT they will be converted again to digital (=> senseless twice conversion => quality loss), using the phase and the clock, and it'll be calculated which pixel should display what color. As the phase and clock can't be adjusted so precisely that a pixel of a picture generated by the graphics card will be displayed by the appropriate pixel on the panel. Means that the picture will be interpolated a little bit, which again means quality loss.
The electron cannons of the CRT need analog signals, that's why VGA is the best for CRTs and DVI would make no sense here.
For TFTs, DVI is the best. I won't get a TFT with no DVI.
You have made a good purchase young padawan
We really need now more reviews at Tom's that include widescreen lcd's sincewide is much better now.
Probably the samsung 91bw is the best widescreen one for the price, specially when paired with a DVI-D cable.
