There is quite a long backlog at Apple, yet the 6-core is readily available at B&H Photo as I write this. Don’t forget to upgrade the 32GB or 64GB memory at OWC.
Reader Bill reports:
Just got an email from B&H that my new Mac Pro is being drop shipped directly from Apple to me today. 6-core CPU, D500 GPUs, 512GB SSD, 32GB RAM. I placed my order with B&H on Dec 19.
B&H also included a great deal on AppleCare and free Parallels Desktop 9.
