I just purchased two 22" HP monitors (yea I know I should've bought 24" ones instead). Right now I have single Nvidia GeForce 7900GS running twin view and the monitors hooked up via DVI. I was wondering if anyone knew if any of the other Nvidia cards (quadro, geforce 8 or 9 series, whatever) might offer better support for multiple monitors. Oh and I currently dual boot vista 32bit and ubuntu 8.04 so if anyone has any links or resources concerning dual monitor setup / multi-monitor setup I would really appreciate it.
As long as you aren't gaming or need highend Graphics support the 7900GS will work fine. Most current graphics cards offer dual outputs. Dual view just shares the cards resources between 2 monitors. Unless you need better performance for Games or graphics programs, you really don't need to upgrade.
