Be careful with the Threadripper jump. It sounds tempting for 8k but that platform cost is a total killer. Ive done high-res workflows and the CPU is only half the battle. If you blow the whole budget on a AMD Ryzen Threadripper 7960X 24-Cores 48-Threads, youre gonna realize real quick that youre short on cash for the motherboard and quad-channel memory requirements. I would suggest sticking with the AMD Ryzen 9 7950X 16-Core 32-Thread instead. It holds its own surprisingly well in Premiere and Resolve for way less money. You might want to consider the hidden costs. A decent TRX50 board is like 600 to 800 bucks alone. That is money that should go into a better GPU with more VRAM or way more NVMe storage. Make sure to check your cooling too. 8K renders will cook a chip if you dont have a beefy AIO. Id grab something like the Arctic Liquid Freezer III 360 AIO to keep things stable. Honestly, the 7950X is the safer bet for your wallet and still crushes 8k timelines if you use proxies properly. Dont let the pro branding on the Threadripper trick you into overspending where it doesnt actually help your delivery times that much. Just keep an eye on your VRM temps if you are doing long exports.
