I personally have this monitor- http://accessories.ap.dell.com/sna/productdetail.aspx?c=au&l=en&s=dhs&cs=audhs1&sku=230-11305
I read the reviews of half dozen top rated monitors, and it came down to the Alienware or the Acer.
It was a close decision, but Im happy I decided on the Alienware. Its a truly excellent monitor, I now use this as my primary instead of my 72" DLP. If you call up Dell and speak over the phone you can talk them down to $400.
I also use the Nvidea 3d vision glasses- http://www.nvidia.com/object/3d-vision-main.html
Overall they are pretty good, but the compatibility with games still isn't as nice as I would like.
Personally I only play with them from time to time, and its rarely for more than an hour before I go back to a traditional view. My only real beef is the loss of vibrancy, but that's due to viewing them through glasses.
When you do find a game they work with, they work really well, and BLOW AWAY anything you have ever seen in a theater.
Also FFXIV does not work with 3d vision. I tried to force it, but it still wont run in 3d mode.
I see folks who claim they can get it to work, but I cant. Ive tried the steps they claimed worked, but I personally think they are full of BS.
