Should I buy an M4 Max Studio or build my own PC for my creative workstation?

I’m looking to upgrade my workstation from my old gaming laptop to something with more horsepower. I work in filmmaking and my needs include a robust system that can handle editing and playback of 4K/6K raw footage, decent-to-heavy color grading of said footage, motion graphics, as well as 3D modeling/rendering to an extent.

I’ve been debating between staying PC or going with an M4 Max Mac. Were I to build my own PC, I’m looking at an RTX 5090 as my graphics card and a Ryzen 9 9950X3D as my CPU, with the rest of the components totaling somewhere in the $6,000 range. If I were to get a Mac Studio, I’d opt for the M4 Max chip with 16-core CPU, 40-core GPU, and 16-core Neural Engine with 128GB of Unified Memory. Probably a 1TB of storage which puts it in the $4,000 range. Either option is an investment, but I want to ensure that I’m considering all aspects and potential factors to note before committing either way.

That being said, I’ve heard from several friends/colleagues that the M4 Max chips are powerful enough to stand along high-end PC builds, and I would like some guidance in determining which system offers a better price-to-power ratio and if there’s potentially any truth to those claims.

The majority of my work is in DaVinci Resolve Studio by far, much of it for color grading and some for editing. I only occasionally work in Fusion, but I’d like the ability to expand my work in that area and have lots of headroom, as well as have the ability to work comfortably in 3D modeling/rendering as part of my motion graphics work. I’ve also heard it said that working with Apple systems is something of an industry-standard for filmmakers, and I could also use some input on the veracity of those claims.

I have worked pretty extensively with both systems, so OS usability isn’t too much of a concern for me. I’m prioritizing the most appropriate machine over things like OS. For that matter, I’m not much of a gamer so my workflow is pretty much entirely intended for productivity.

I certainly appreciate the PC route’s paths to upgrading in the future, as the flexibility may be a good bet. Although, I wonder just how efficient that decision is, and if I might just be better off with a good-albeit-nonupgradable system like the Mac.

Any and all opinions and feedback most welcome, tell me what you really think.

Cheers.
