Not sure if @MacSparky needs a GPU upgrade, or was speaking hypothetically, but the Blackmagic external GPU is available if the need arises.
External drives
The USB 3.1 specs (etc.) are actually gigabits per second, as the b is lower case. Convention is to divide this by 10 to get gigabytes per second, which accounts for creating packets, checksums, etc.
I have a Sabrent Rocket 2T drive that works well. It’s an external NVME drive connected to Thunderbolt 3, and is rated at 2.4 GB/s (gigabytes/s) read, 1.2 GB/s write. I just benchmarked using Diskmark and compared to a couple of USB 3.0 drives and the internal iMac Pro SSD.
Benchmark (MB/s)
| Device | Sequential Read | Sequential Write | Random Read | Random Write |
|---|---|---|---|---|
| iMac Pro internal SSD | 2578 | 3045 | 269 | 156 |
| Sabrent Rocket NVME 2T TB3 | 1492 | 1190 | 169 | 153 |
| Crucial MX100 SSD in Sabrent USB 3.0 case | 405 | 211 | 9.8 | 98 |
| WD My Book 8T USB 3.0 | 150 | 108 | 29 | 9.8 |
| Synology DS918+ NAS over 1Gb/s ethernet | 103 | 103 | 16 | 3.3 |
| WD My Passport 4T USB 3.0 | 58 | 103 | 46 | 8.5 |
