Hi there!
My husband and I are pretty avid gamers.
For his birthday, I ordered him a VooDoo Hexx and based on this article at Tom's Hardware:

I bought him a Samsung SyncMaster 192b to go with it. Newegg shipped quick and we got it the next day.
We promptly hooked it up to his existing machine to 'check it out.' Not one dead pixel and it really looks fantastic. I noticed no "ghosting" at all when he plays and he's remarked several times since he got it that he's really impressed. It was a hefty chunk of change ($825+), but since he 'dinged' 50 this year, I figured he deserved something super special for his birthday.
I would not have recommended an LCD gaming monitor prior to this one. Now I'm thinking I would love the desk space and cooler room temperature, so I may just have to replace the other three CRTs. =)
Just be careful on the dead pixel thing - the manufacturers only warrant returns on a certain number. For example, the SyncMaster when I ordered it would only qualify for warranty replacement for 8 or more dead pixels. My love of the monitor would certainly have waned quickly if I had to deal with that.
Hope this is helpful.
