Both, photo and video are both important in my situation. I have always built my own desktop systems and I enjoy the real estate and resolution of a 32" 4K monitor when working on photos or video. I have an older XPS15 for travel that works fine for photos and light video editing in Resolve Studio. Great for culling photos at night or getting out some quick video clips for friends/family on social media. When I'm at home, the laptop is connected to a 27" monitor and most often used for non-photo or video related tasks.
My main desktop machine is one I built back in 2017 that, at the time, was about top of the line with a 4GHz I7-6700K (overclocked 15%) and 32GB Ram, Samsung nVMe SSD. I wasn't doing much video, so I went budget with a GTX-1060 GPU and that served me well until I got into Resolve and more demanding video production. A couple years later, 64GB and GTX1660 GPU followed along with a couple 1TB SSD's for working media storage, one for photos, one for video projects. About 2 weeks ago, I got a great deal on a lightly used RTX3090 from a guy that just upgraded to the RTX4090...what a difference for video!! Somewhat surprisingly, the I7-6700K is holding it's own for video editing...I was concerned about that when I added the RTX3090, but it's feeding the GPU very nicely...still got some life left in it.
There are two shortcomings to the system I need to consider in the next year or so...one, the system is not Win 11 compatible and two, that series of CPU does not support hardware decoding of 10-bit, H.265 4:2:2 video by the internal GPU...nor does the RTX3090. Why is that important...well that's the most practical format to shoot with my Z9, especially 8K...quality and color grading capability in Nlog is outstanding and file sizes are manageable. I can get a lot of footage on a 512GB card...not so if I shoot RAW and we all know the price of the fastest 2TB and 4TB CFx cards!
Win 11 is not a priority for me, but there would be a considerable increase in proxy or optimized media generation in Resolve with a newer CPU. No real impact for photo editing, though. I think I'll stand pat with what I have until sometime next year and see how the new CPU's and GPU's shake out.
When I travel, the working media SSDs travel with me and I connect them to the XPS laptop...and they're backed up to offline storage at home before I leave. When I return, they are reconnected to my desktop system and I'm good to go with whatever I've done while away. Very transparent for my needs and I do backup daily work and raw files to a 2TB SSD when traveling.
I can't imagine not having both systems...sorry for the long-winded reply...some context might be helpful for others.
Cheers!
