Honestly, if your looking for long-term stability over just raw frames, you gotta consider the thermals and power draw. Some of these newer chips get *really* hot, and that can sometimes lead to weird stability issues if your cooling or motherboard VRMs aren't up to the task. - Check out the "PCPartPicker" build guides to see what cooling setups people are using to keep things stable under load.
- Consider the AMD Ryzen 7 7700—it's basically a power-efficient beast that stays much cooler than the X-series, which is great for longevity. I mean, I've seen plenty of folks regret pushing there chips too hard just for a 5% gain. Definitely check "Gamers Nexus" on YouTube for there deep dives on power consumption and temps. Better safe than sorry when your doing video editing and don't want a crash mid-render!

^ This. Also, i was unfortunately pretty disappointed with the newer 9000 series lately. They just didnt live up to the hype for the price. Since you mentioned video editing, you might find an 8-core chip kinda limiting for long exports. I had issues with my old rig lagging during heavy renders and it was honestly a nightmare. I would actually look at the AMD Ryzen 9 7900X. Its usually under $380 these days and those 12 cores are a massive step up for productivity while still being a beast at 1440p. It does run pretty hot tho... like, really hot. Dont skip on the cooling if you want it to stay stable. I usually suggest the Thermalright Phantom Spirit 120 SE to keep things from throttling. You should definitely check out the Puget Systems hardware articles. They do deep dives into how these CPUs handle specific editing software which is way more helpful than just looking at raw gaming FPS.

7800X3D is a good choice.

9700X.

Man I wish I found this thread sooner. Would have saved me so much hassle.
