Indeed, amazing lcd screens and at amazinly exorbitant prices:http://store.apple.com/1-800-MY-APPL....18.104.22.168.0.1.0
The 30" one that you mentioned it $3400. The 20" is $1300. Pardon if I'm not impressed.
But this is a lost argument anyways. If you want to spend enormous amounts of money on widescreen lcd displays go ahead. At 16ms response time, it should be reactive enough. Your main problems for gaming is thus:
1680 x 1050 optimal resolution :20"
1920 x 1200 optimal resolution: 23"
2560 x 1600 optimal resolution: 30"
Yeah, yeah you can always decrease the resolution down to something lower, but the quality will deminish greatly. The problem with high resolution screens for gamers is games do not yet support high resolutions yet or widescreen resolutions natively (most require a .ini file modification that while easy to do, results in "stretching effects). The other and most important problems is the hardware requirements to drive such a screen. Tell me, what resolutions do YOU enjoy playing at? 1024x768, 1280x1024, 1600x1200? While you can play a lot of games at 1600x1200 and higher, the performance takes a hit and unless you have a powerful enough graphics card, your game will be darn near unplayable. These screens are great for graphics design (the main use for Apple products), but while the response time is perfect for gaming, do you want to spend an additional $600 or so for an ultra high end destop graphics card just to run it? The 30" states clearly that it requires the Nvidia 6800 Ultra DDL card at a minimum. However, it is most likely that if you are spending that much on a monitor, you probably already have an ultra high end gaming card. The thing is, since this is a notebook forum, my initial thoughts were that you were going to plug this into a notebook's dvi output plug. If this is the case, check the specs on the output as the resolution is limited in many notebooks.
Gaming, possible but hardware requirements may involve additional expenditures.
Don't get me wrong, if I had $4000 to burn, I'd love to have a huge display. Beats a TV at that size. I think that for gaming, get something between 18" to 19" with a native resolution of that which you normally game at. For gamers, speed is almost everything, sacrificing a little quality to get the frame-rates up especially in FPS games. Review sites and alienware notebook people can brag about playing at 1600x1200, but for how long game-wise will their machine be able to run newer and newer generation games at those resolutions. Me, I'll take 1280 x 1024 on a regular lcd screen anyday over 1600x1200 just to get those extra fps in Unreal 2K4 or Farcry.
