Modern LCD's are excellent for gaming, they just have a bad reputation because the original ones were terrible.
An 8ms black-white-black LCD can pump out 375 frames per second, and unlike crappy CRT's it refreshes the entire screen simultaneously rather then scannning up and down at 70Hz or whatever like the old school CRT. I doubt your Video Card can exceed 375fps?
However, make sure you get a high contrast ratio too (500:1 or better) as some companies drop their response time by lowering the contrast ratio. The contrast ratio represents the colour difference between white and black pixels, higher being better. 350:1 is ok for gaming, but a$$ for wordprocessing as the black/white difference is soo low.
As for brands: Viewsonic, Acer, NEC, ...
