Yea if you max out the hardware and add AppleCare it's $18,023. I was curious how much I would save with my student discount and it was about $1,800 cheaper.It's expensive to fully cram a Mac Pro with every feature possible. It comes up to over $18000 US.
RAM is the limiting factor for abinitio quantum mechanics and DFT calculations. The more you've got, the bigger the system you can study. It's mostly done on clusters, actually but an octo with 32 GB...Is there any use for such a configuration really? what can someone do with 32GB of RAM that they cant do with 8GB?
