TN's are not bad for the average user. Or even for most PC Gamers. But if you have the money, you should always consider a superior quality product unless you absolutely need multiple monitors.
But you paid just $150 per LCD. That's still acceptable. But there are SO many people buying TN panels for like, $300-$500 each, and it's ridiculous. I don't care how fast their GTG response time is, it still looks like crap and ghosts and blurs with motion.

Anyway, the technical reason why LCDs don't cause eyestrain like CRTs do is because CRTs are very much like fluorescent bulbs in that they are constantly flickering. This is why using a higher Refresh Rate is easier on the eyes. But LCDs are very much like incandescent light bulbs in that they just glow. So, it's like the difference between staring at a bright fluorescent light from 2-3 feet away and staring at an incandescent.
But LCDs can still cause eyestrain due to the fact that the eyes are focused on the same object for an extended time. Of course, setting the LCD's brightness too high will also increase eyestrain - especially in the dark
. I have tried using my computer in the dark, but it is much harder on my eyes, so I just leave the lights on. That's how I can last 12-18 hours on my computer every single day.
Incandescent light bulbs also flicker at 50Hz or 60Hz (whatever the frequency of the electricity is).
LCDs cause more eyestrain than CRTs for me because of the stupid blurring/ghosting. With most desktop use it's fine because the only thing really blurring is the mouse. But it's hard for me to play a game on one for too long.
There's also the phosphor decay to think about when talking about CRTs. That is, how long it takes them to release all their energy and turn off again after being hit by the gun. Many CRTs have been made - most of them TVs - where the phosphor decay matches up perfectly with the refresh rate, so that each phosphor only turns black the instant before it's hit again. This reduces eye strain a lot.
Another cause of CRT eye strain is improper convergence and focus. The blurry image you get when either of these are out of whack makes your brain keep trying to focus your eyes to make the image clearer. This effect gets more pronounced depending on how much of your visible area the screen is taking up (such as with a large screen, or if you're sitting really close to it). If the picture on your screen isn't perfectly sharp then you need to adjust these. If adjusting them still doesn't fix it, then it mostly likely means that you're running at a resolution greater than what the shadow mask or aperture grille can handle (resolution > number of subpixel triplets) - which is very common on CRTs.
Also, just running at a higher refresh rate isn't always a good idea. Each CRT has it's own optimal refresh rate at each resolution, which is based on the accuracy of it's electronics. Take the GDM-FW900 for example: at 1920x1200, it can go up to 98Hz. However, at 98Hz the picture isn't as good as when it's at 85Hz. So this is the refresh rate you should be running it at.
