DL-3900 does dual display up to the resolution you need I think. Its USB3 so should work on any laptop. See the resolution limits on the list. I don't think they are manufacturer specific, and a trial dock is a lot cheaper than an entirely new non-standard laptop.

Dragon788,

Thank you for your reply! I'm uncertain as to which device we would be looking to buy from the list, but either way I'm not sure it would be a very good solution. Without buying one to test on the main question would be how does the performance differ between the USB 3.0 dock and the USB 3.0 to DisplayPort adapter which we've already purchased?

Another thing to note:

We had Dell send us a test system with the ATi card and that also had very similar results. The drivers seemed to remain the same but the Aero theme disabled and we got poor performance from the system once all 4 monitors were at 2560x1600.

We'd really like to know if there's an .inf file we could edit to allocate more RAM or processing power for the display to increase performance, or something along those lines...

Those are some pretty steep requirements for a single portable machine. One thing you might investigate is adding a second machine on/under his desk and running Multiplicity (Stardock product) or Synergy (Free Open Source multi-platform) or InputDirector (free for non-commercial) so that you split the load across both machines and can run dual monitors from each. My biggest issue with the M4700/M6700 has been that the Nvidia cards are supposed to be able to do 4 monitors themselves, but there doesn't seem to be an option to disable the built in LCD and just drive 4 externals.
