Looking to buy a new LCD monitor

Hey guys, I've been using a Viewsonic G773-2 CRT up until now and I was looking to switch to an LCD one. Now I did a bit of looking around both online and in local stores, and I've narrowed the list down to these:

- Viewsonic VX922 (2ms)
- LG 1952T/TX (does anyone know the difference between the T & TX?) (8ms)
- Samsung 931BF/940BF (2ms)

I chose the Viewsonic because the CRT I have has always been good and because the review said it was great for games. The LG has a high contrast ratio (1600:1) and I hear good stuff about it. And the Samsung I saw in store and looked very nice, and it claims to have a 2000:1 contrast ratio as well. Oh and does anyone know what the difference between the 231BF and the 240BF is? What I use my computer for most is tied between games and video, then internet/school work, then photo editing. Based on all these things, which one should I get? The Viewsonic and Samsung are both $299 and the LG is $279 so price isn't really an issue either. Any help would be appreciated!
