Well, there are a number of opinions on this one, and I'll try to help you out as much as I can. First off, remember that there is no right answer in terms of fulfilling your needs, but you'll get quite a few opinions here based on personal experiences.
If you're looking for an LCD (and given your links, I'm assuming you are), then there are a couple of things to look for in a display. First of all, make sure that it's an 8-bit display (colors matter), and that it has a high contrast ratio- 1000:1 would be sufficient. You won't need an 8ms monitor, unless you're planning on running Doom3 with your 8800, but since you asked about PS, we'll assume you aren't.
Basically any monitor that you get within those parameters will be fine. Go for bigger name brand- Samsung are descent, SonicView, LG, and maybe Gateway. Apple displays are nice to look at, but I doubt they are that much better than the rest (hint- Phillips makes the LCDs for the ACDs, and they also own LG).
A wide pannel, doesn't mean that your image will be distorted, just that you'll have more horizontal real estate.
Cheers.
