One thing to keep in mind, even with a lower refresh rate, LCD's aren't going to flicker in the way that CRT's used to. Why? Because they simply work differently.
When a pixel lights up or gets redrawn on a CRT, it's an almost instantaneous change, whereas on an LCD it's more of a gradual type of thing, which is where response time comes in to play, and why response time isn't even a specification on CRT's.
Think of it this way. A CRT is like a stoplight. At the exact same time the red light turns off and the green light comes on. LCD is different... the red light would fade away as the green light fades in. It's a more gradual process, hence no flickering.
Response time, in a nutshell, is how long it takes the pixel to "change"... faster = better but even at 2ms it's still a lot slower than CRT's, which is why LCD's have such a bad gaming reputation... but it's being figured out that you simply don't need a zero response time to get clear, sharp graphics on a monitor.
If you've ever used any first generation LCD screens (such as the old, old laptops.. black/white screens) it would have so much streaking in the graphics it was nearly impossible to play even the simplest of games... but technology has come a long, long way since then!
I have a HANNS-G HN199D 19" standard LCD... 8ms response.. and yes with crappy speakers!... but even 8ms is more than enough for good AH play. The bright, clear display more than makes up for the speed. The only time I notice any streaking at all is in a tank, fully zoomed in while scanning the horizon quickly.. but even that I've gotten used to. I'd imagine a 2ms, or maybe even a 5ms would more than enough correct that issue.
