I have a Samsung (191T Plus) for my desktop, and I will be plugging my 8790 into it via DVI. Samsung LCD color and picture quality are superb IMHO. The black screen is black, not dark green or purple as some other LCD monitors tend to be, and it was easily calibrated using a Gretag Macbeth Eye One, so it very closely matches the output of my Epson 820... and I'm using the VGA input. Can't wait to upgrade my desktop video card to use the DVI.
As a photographer, accurate color is as important to me as minimizing the acreage occupied on my desktop by a monitor. The latest Samsung line also offers a thin bezel (the border around the actual screen, less than 1 inch thick), which makes the screen look bigger than it actually is. (Or does it make the monitor look smaller than it normally would be? *shrug*) Ultimately as Kakaze stated, a top end CRT is the best choice when it comes down to accurate digital color, but if you really want an LCD I highly recommend Samsung.
