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 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 http://www.digitalyes.com.au/prodView.asp?idproduct=31378 but found they did not work to well with my layout.

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).
