A fanless card such as ATI Radeon HD 5450, consumes less than 20 watts
under full load. And no noise...

In case of multimonitors, take care to the slot. Most of the MotherBoard
have only one graphic slot.
Best regards

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
