Yes - quite often... financial markets require these setups - a few thousand dollar are nothing compared to the cost of a single mistake cause the wrong window was covered up :-) > Is Matrox the best choice or do you recommend a different card? I can recommend matrox on linux but only with their older G450/550 based cards. There are other options though. I would really recommend going with an appian card if you want to use only one slot. Other than that, you can run a dual head AGP card and you can also find dual head PCI cards - you can run i.e. one ATI AGP card and a GeForceFX PCI card. That's what I run at home. If you want to spend a little more money, dual PCI Express cards will work well. Matrox also has a G550 with a PCI Express 1x. That way you can run multiple matrox cards without having to have a SLI cabable board. > What kind of 'usability' have you seen with this configuration? Can't recommend it for working. The borders are annoying if you have anything that spans screens. If you have separate things, its hard to keep track on more than 2 screens if you run random apps. Dual 24" panels will be your better choice. If you want anything else, you can get cheap plasmas for the same cost of this setup with a VGA in. Also, run the panels at native resolution will give you much much better clarity of the picture. Peter.
