Question : Problem: 3 monitors on a single PC

Hello Experts,
My boss wants me to install three monitors on one pc that could have a differen window in each monitor. I have been reading people that have achieved this and it seems that I could install two dual-head video cards to get this done.
Since I have not done this in the past, can some one tell me if that is the way to do it? or if not, what would be the most cost efficient way to get it done.

Thank you in advance,

Installing a Four Head card would be better.  NVIDIA and othe manufacturers make card that have two specialty DVI connectors that then branch into four (two each) DVI connectors.  Then your boss can have four monitors if he wants - and you don't have to deal with conflicting video boards.
