Dell workstation
I don't know what your budget is, but we just purchased and configured a couple very nice Dell Precision 7810 Desktops. They each had 64GB RAM, 512GB SSD, and a 8 core Xeon chip, as well as a slightly upgraded NVIDIA GPU. These machines ran about $3500 each, a little on the high end, but quite nice. There were also a couple 24 inch monitors that we purchased with each desktop that ran about $350-$450 each; I don't remember the exact price. Basically, each desktop came with two monitors and we spend just under $4000 for each setup.
If that is too much, we could get the same machine with less exorbitant specs or simply purchase a couple Dell XPS desktops. I know that these are pretty decent but I'm not sure about the price right now. They'll be quite a bit cheaper. We have a pretty good relationship with Dell so we typically purchase from them.
So, I guess the first question is: what is your budget? That would be a good starting point for this conversation. Maybe, next time you're at the SimCenter, we can talk about it?

vertical strips on 17in mac pro laptop
Today, my 17inch mac pro laptop (5 years old now, hostname "ace") has a vertical strip in the middle. (It occurred once in the spring 2015, but went away on its own).
After some online research, I pressed the glass screen for a few second, and restart by holding CMMD+Ctrl+P+R. The vertical strip went away.

Later in the afternoon, the same vertical strip come back again, after some overheated use.
I tried press the glass and CMMD+Ctrl+P+R again. The vertical strip was still there.
