If you're looking for a bargain high powered mac, the mini is where its at right now
- CPU clocks reasonably high, is a 6 core
- Can add a monster GPU (or several of them) via thunderbolt 3 enclosures.
- Can stick 64 GB of RAM in it
- Can hook up plenty of external storage via either thunderbolt or 10 gig ethernet
- No monitor tax for a display you probably don't need or want (looking at you, iMac pro - which starts at $7299 AU locally)
Sure, its not as nice as a Mac Pro 7,1, but its a fraction of the cost and will get a lot of the performance.
If 64 GB and an external high end GPU is not good enough then unfortunately you need to pay the price...
Here in Australia, the entry price to the mac pro is about $10k AU. For 256 GB SSD, an 8 core and a freakin' RX580. That spec should not exist, it makes no sense putting a $200 GPU inside of a $10k machine. Ditto for cheaping out with $50-100 worth of SSD.
If you want any sort of "high end mac mini plus GPU in a box" beating spec (in all things) you're looking at *at least* 16k Aussie (8 core, 96 GB + RAM, 1TB SSD and a single Vega II GPU).
Thanks for the tips. I will have a look at the mini and other alternatives. You know, I thought 32 GB RAM would be plenty, but recently while working on a big Photoshop file, I ran out of scratch disk. Closed all applications and restarted Photoshop, but it didn't help. Camera Raw files keep getting bigger too. I don't need a high end GPU, but you're correct I need to figure out if 64 GB RAM is going to be enough.
