I have an old set up too. I've been thinking about updating it. I used to carefully build my PCs back in the old days and obsess about every component, but this time around, I just got a gaming PC on Amazon, of all places 😌 The only update I've made is RAM and a Graphics card (8 GB) before all prices went through the roof. I hope you're able to find compatible hardware for yours. Video editing takes a lot of computing power.
