Needing to upgrade PC/monitor/setups and trying to get an idea of what kind of setup those who are extremely active during the day looking at charts are using.

At this point looking into stacked monitors, just not sure if I should go 4-5 regular monitors that are stacked, or go with two widescreen, etc... What kind of mounts to use, making sure the PC and video card can handle it, etc...

Any thoughts?
