I can't speak for that exact monitor, but I have used the Samsung SyncMaster 730B [I could be wrong, but it's similar] and found that my NEC had better picture. Games look pretty good on that one, but even the Windows desktop looks that impressive. One thing I find about some LCD's is that the picture quality is just not crisp and sharp like a CRT, however the one I am using is.
Hopefully someone else here has experience with that exact model.
[Edit: Maybe it would help to answer your full question. If you are missing DVI you will not be hurting that badly. I am hard pressed to notice a difference myself. If you have a good 8ms or lower LCD, you should be fine either way.]
