Quote from taq:
I was thinking about the same machine but will it be able to run 6 monitors? what changes should be made?
sure... but the bandwidth available to that video that will vary... in other words... you wont get the "top" performance for it but who cares... you are not modeling molecules in 3D or playing games on it..
basically, what I am trying to say is that unless you have a Xeon, your performance will be halved on that x16 slot if you use two video cards.. but this is not the issue... you dont need huge amounts of bandwidth to display 2D..
anyhow, you will need to get two 4 port cards to address those 6, so you can expand up to 8...
some of the guys here like ATI..

I prefer Nvidia because I have experience with them..

as well as Matrox, which again, I have experience with...

in the end, compare them... froogle them for the best price and get a matching pair... and of course, if you can... get DP assuming your monitors have DP's and depending on size(monitor)...
