What would you recommend in a desktop? At least 16GB RAM, a SSD, a video card (what specs?), and ???
The Thunderbolt3 port that
@kelemvor mentioned seems to be discussed only in the laptop context.
I'm in the market for a desktop for working from home, and so I was considering a bare-bones cheapie, but now it occurs to me that I could use it for video editing.
I did a bit of research.....please keep in mind that these are my thoughts only, other people will have different ideas that are just as valid and maybe more so.
To start with I've always preferred ASUS motherboards and AMD CPU's, so I'll go with those. They've always worked for me so I've stuck with those two....sort of like always buying Fords and thinking anyone who drives a Chev is crazy.
So I picked an ASUS Prime B550M-A.
It has 4 memory slots and allows a maximum of 128 GB. I'd start with one 16 GB SIMM and go from there. This gives you plenty of room to grow as your photo/video editing app is upgraded and your data files get larger.
It has an AM4 slot for an AMD processor. I'd go for a Ryzen 3.....just pick the cheapest as long as it's around 2.5 GHZ. Processing power won't be what limits you.
You can get an SSD or an SATA hard drive, whichever you prefer. The vendors I checked offer about 10 -12 times the capacity in the SATA hard drive for the same price as the SSD. That said, I've never come close to maxing out my existing 500GB hard drive and what I looked at was in the order of 4-12 TB. The SSD eliminates moving parts which is probably an advantage, however it's been at least 25 years since I crashed a traditional hard drive.....pick whichever you like, both will work with the ASUS board.
The ASUS board has a built in video card, but you'll probably want something better, particularly if you're working with video. This is where you want to spend a bit of money....probably something midrange like a Geoforce RTX 2060 or 2070. I checked local prices and the cards were around $500 CDN.
You need a monitor, but that's been covered in other posts, and a few bits and pieces that I'm sure you already know about.
If you have a few dealers close to you, see who can give you the best price on the full system.
