Thanks for your inputs Jo.
Yes, I'd love to test this out, but I'm not sure if I'll get the chance yet. Still looking into it. I "may" be able to get a used server with these specs for a discount.
If it were to work, TG2 would have 8 cores available, which would significantly speed renders up.
In the meantime, I am going to wait until TG2 supports multiprocessing.
