$5000 for imac pro(+applecare)? that is bonkers. $6000 is even more crazy. You can get more storage, better gpu, more options for network for much less. And you wont need to deal with apple geniuses to fix the issues.
Those alternatives don’t run macOS.
For under $2K you can have a machine that competes with newer machines that cost twice that much. If you're a professional creative type, these machines are the real deal:
The Most Powerful Mac Is 6 Years Old and Not Sold By Apple - https://www.vice.com/en_us/article/8xkq8k/mac-pro-upgrade-co...
the Mac Pro 5.1 was designed to accommodate up to 12 cores: “Even though a single core isn’t fast, imagine having 12 of them for video editing and audio—those cores together are faster than my brand-new MacBook,” Mazzarolo said. The new iMac Pro can have up to 18 cores; new MacBook Pros max out at four cores.
The 5.1 can take a whopping 128 GB of RAM, which is equal to what a fully upgraded iMac Pro can take and double what Apple says the trash can Mac Pro maxes out at (it’s worth noting that the RAM used in newer Mac computers is usually faster)
The 5.1 can be modified to use modern SSDs, which Mazzarolo said are in some cases faster than the ones used in the new iMac Pro
The 5.1 can use almost any brand-new graphics card from most manufacturers, which is the main reason why a fully souped-up, old Mac Pro can outperform new computers. “With some rendering engines, the AMD cards that Apple uses [in new Mac Pros] don’t even work,” he said. “In general, even mid-level graphics cards we put in are as fast as those in the iMac Pro. We can put in better cards and we can put in two of those.”
On the Facebook group, Mazzarolo posted benchmarks of one of his custom-built rigs playing 5K, 6K and 8K RED RAW video clips against current-model Apple computers. A new, 15-inch MacBook pro and a recent “trash can” Mac Pro weren’t capable of playing the video at more than 8 frames-per-second. His custom-built model was able to get 24 fps in each case.
