Did you read that I have XP? I only have DX9 on my PC, which is perfectly fine. Even though I have an X360 Id much rather have my games running at 60fps at 1080p than 30fps at 720p. To each their own.
Well, like you also said, to each their own. I see absolutely no reason for a 3 (let alone 6) monitor setup for gaming. Maybe for day trading stocks, but nothing else. I couldn't care less if I either turn my eyes left or right to see a car on my side, or to quickly press a buton to see the same thing on my single monitor. And it would be more than a grand to get a 6 monitor setup (worthless for anything other than PC eye candy) with a very thin bezel, how much power would they consume alltogether, and would it run at 60fps on the same setup as a single monitor? I find it strage you say you have a hard time doing 3D in DX10/11 because Nvidia has native support for stereo 3D in Vista or Windows 7 only (DX9/DX10/11 only not XP), and the reviews say it works great. I have to use D3D drivers or IZ3D drivers for stereoscopic 3D, both of which work fine for me. You can call 3D a gimmick, but I call 6 monitors a gimmick, especially since there are thick bezels in between monitors. If the bezels were .01" thick, then maybe I could agree with you. I've seen youtube videos (and even at Bestbuy as a console setup) of a 6 monitor setup and it looks retarded. Like looking through a paned window:

3D, however, looks amazing as everything jumps out at you. I don't play like that daily. Just once in a while to get a treat or to show it off. An ultra highrez monitor shrunk to 23" that supports 2560 x 1600 would be awesome cause there would be no need for FSAA. Until then, a 56" DLP would probably take up more real estate as a 6 monitor setup, consume less power, and be cheaper. It could also be used as a regular TV, monitor, and have no thick bezels inbetween. It could also do 3D if I please.
But whatever, to each their own.
