We mentioned in the initial post to this thread that an AMD CPU probably makes more sense.

While it may seem like a lot of money, we do have a few ways to help justify the cost.
  • We sold a pile of old parts and other things which easily funded more than half the cost of this system. So, in a convoluted way, that was "free" money.
  • We plan to keep this computer for five years, so the cost per hour is not-so-scary.
  • We are debt-free (highly recommended!) so we have a bit of financial flexibility.
  • We don't use drugs, alcohol or tobacco and we don't have cable TV. Those kinds of habits can really add up!

Gulp! Wow!!!

I don't think my budget is going to be anywhere near that!

I just need to drive six (6#) or so monitors and run lots of VMs. So I'l be aiming for at least 128 GB of RAM.

A friend of mine's son was recently given a very nice AMD system. Twelve core or something. WinCrows seemed pretty snappy (as did, of course, Mindcraft... Sigh...).
