I came across some matrox monitor dividers, Anyone have prior experience with Matrox products?

Question

I currently have a Pny GForce 8400GS in my computer with a 2 monitor setup. I want to add another 1-2 monitors with this (http://shopmatrox.com/usa/products/categories.asp?CategoryID=80&Column=2),
Anyone have prior experience with Matrox dividers or have any opinions?
Are there any drawbacks(ie. slower graphics)
I plan on Daytrading + some gaming. Thanks in advance, i appreciate any input. ty

Answer 1

A couple years ago my company was experimenting with the 3 headed display (aka cockpit) and used a Matrox card to drive it. I don't recall the model info but the card worked well for business applications. We also did some imagery work with it, but the performance didn't match some of the higher end nVida based cards we had for our dual head systems.

We also used the Matrox2Go cards to get dual head setups on a laptop, but those really are limited to business type usage. The performance really wasn't adequate even for some of the video demos we prepared, but it seemed to be the only product that came close to what we wanted.
