2nd thoughts
I've been a 2 monitor user for years and have avidly lusted after a 3-screen setup (Bill Gates reportedly has a 3 screen setup with work on the first 2 and email live on the 3rd). But now that it's practical (matrox digital plus drop in LCD prices), I'm hesitating. Although, for a non-gamer, there is an obvious advantage in having separate real estate for 3 applications, there is also the resolution issue to consider. In my current setup, I'm running two 20in flat screens at 1600x1200 res. That equates to 3200x1200. So, if I switch to 3 screens, I'm only getting a bounce to 3840x1024--that's essentially lower res. In my case, I'm doing word, excel and photoshop as my main tasks. I don't think the tradeoff gains me much if I end up working with smaller spreadsheets, shorter text and lower res photos.
Bottom line: I'm still waiting for the gpu muscle to support 4800x1200 on 3 screens. I need to explore the possibility of a non-matrox solution--installing an additional single graphics card-- but I don't know if Windows can readily integrate a 2 outlet + 1 outlet installation into a 3 screener.
