Hi Rob, Well apparently Yahoo ate my first response to this, so I'll try again.
I didn't actually use 12 GB in my machine, though I have room for up to 24GB total. However, 4GB sticks are not cheap yet, so for the time being 6GB is plenty. I use the memory to run virtual boxes to do optimizations in Tradestation since you can only run one Tradestation instance at a time on 1 operating system. Looks like other people have responded regarding the video cards. I think it is good to have SOME sort of 3d hardware support but not necessary to have the type of card that the gamers use in SLI or Crossfire.

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...?
