Perhaps the eVGA driver is compressing the data before transmitting on
USB 2.0, followed by decompression in eVGA hardware?
The specs for the card say,

Hello,
USB 2.0 for video? It is too slow. 1280x1024x32 bits @ 30 frames per
second means 1258 Mbit/sec.
USB 2.0 speed limit is 480Mbit/sec.
Best regards,

Hi,
A great option that I use for additional monitors is a video card
that uses DisplayLink technology, such as the EVGA box (that's what
I'm using) http://www.digitalyes.com.au/prodView.asp?idproduct=49733
<http://www.digitalyes.com.au/prodView.asp?idproduct=49733>
This allows you to run multiple monitors using a USB connection. No
internal video cards (other than the primary monitor).
Great for charting etc. Do a search for Displaylink on YouTube.
I started with the

they did not work to well with my layout.

Paul,
That was super helpful. Thank's very much.
Yeah, the little bit I'm stuck on at the moment is the video
card. I need to run 3 monitors so I guess I need two cards. I
don't need anything spectacular on the 3D front clearly. Just a
fast an solid card for charting etc. Any suggestions...? Or does
your original choice still apply.
I notice you put in 12Gb of memory!!! Wow. I thinking of reducing
the memory of my new system. I have been running an 8Gb memory
Mac Pro and the most memory I have seen myself use if about 2.7Gb
of physical memory... so I'm thinking 6Gb will be enough. Maybe
you have some very large AB databases or lots of symbols...? (I
only look at about 30).
Thanks again
Rob
