Basically I could not utilize a card more than 50%... as soon as it went above that, my host CPU would also go up to 50% and then follow the UAD processor along. If I used 70% of my UAD setup, my host would also be at 70%.

We need to talk. I have had a similar problem for a long time, even with my old box.
My issue was with Cubase any UAD-1 cards, and it did not matter if it was a card on the mobo or in the Magma chassis, I had the same problem:
Once the UAD-1 CPU meter approached 70%, the CPU meter in Cubase started wigging out (100%). 68% was fine, but 70% seemed to be the magic number.
I have been working on this for AGES with everyone I could think of (Lynx, UA, Steinberg, etc.).
It looks like my issues are solved now with a new version of the Lynx driver that is in beta. It was sent to me by the Lynx tech support guy who has been working on this with me for a year and a half. The new driver appears to have solved this!!! I have tested it extensively with the new "feature" enabled and disabled, and it is 100% repeatable.
Feature on = no problems
Feature off = problems return as before
I am thrilled! I have regained 30% of my cards' power!
Losing over 30% of 3 cards is like only having 2 cards.
