The Mac Pro has been sent to Marques Brownlee for a review, and he's impressed. This video will show you what you can expect if you're planning on upgrading.
The specs are insane, and it's the fastest machine he's ever tested. I agree with him: it's not going to make the videos better, but it will make him try new things like shooting in 16K if he can when that happens. I will not be able to get my hands on one of these; it's just out of my league, but if your business can afford it and you're going to use the machine to its full potential, you'll enjoy knowing you've bought the top of the range in the world of personal computers across all operating systems and brands.
This might not be for photographers alone, as we don't need all this power if we're editing one image at a time. But, I wouldn't say no if someone gave me one, that's for sure.
The design looks as good as it did on the launch day. Even if the monitor stand costs an additional $1,000, it's well built, does what it says it will, and the investment in the machine justifies it. It's going to be with you for a few years, so you might as well get the best you can get.
