I have a Viewsonic VX910 and I can detect absolutely no ghosting, even in very fast paced games. An LCD will give you brighter, crisper, sharper color and is much better for non-gaming use. Really, the only disadvantage of LCDs is poor blacks, and that's slowly going away.
Go for the 2005FPW. Most new games support widescreen, such as HL2, Doom 3, Far Cry, Enemy Territory and UT2004. And if you want to play some old games, you can have black bars on the sides.
You'll get an advantage in FPS games with a greater FOV. Widescreen is the future.
