Man, you are gonna love the jump to AMD! I made the switch last year when my old rig was basically a space heater in my tiny studio during a July heatwave. I was working on this massive 4K documentary with tons of multicam clips and my Intel setup just kept thermal throttling. Swapped everything out for the AMD Ryzen 9 7950X 16-Core 32-Thread Desktop Processor and it was seriously like night and day! Exports that used to take 20 minutes dropped to under 10. It is incredible how much raw power this thing has. Dont get distracted by the 3D V-Cache hype for your line of work. I actually tested the AMD Ryzen 9 7950X3D 16-Core 32-Thread Processor for a week because I thought the cache would help with my timeline scrubbing, but it was actually a bit slower for heavy rendering tasks. Here is why you should stick with the standard chip:

• The standard 7950X has higher base and boost clocks across all cores. Premiere Pro absolutely craves that raw clock speed for crunching 4K/60 exports.
• The X3D chips have this dual-CCD setup where only half the cores have the extra cache, and they run at lower speeds. Sometimes Windows sends your export task to the slower cores and it just bogs everything down. Its a headache you dont need when youre on a deadline.
• Since you are on a two-week deadline, waiting for 9000 series stock is risky. The 7950X is a proven monster and the value is fantastic right now. Pair it with a beefy cooler like the Noctua NH-D15 chromax.black Dual-Tower CPU Cooler and you will be flying through your next gig. Enjoy the upgrade, it is gonna be life-changing for your workflow!

In my experience building high-end edit suites over the years, the AMD Ryzen 9 7950X 16-Core 4.5GHz is definitely the better play. I've tested the 3D variant and while it's a beast for gaming, the lower clock speeds on the cache-heavy CCD actually slow down your renders. You want that raw frequency for 4K exports. Since you're in Chicago and need this done fast, I'd grab the ASUS ProArt X670E-Creator WiFi Motherboard too. It has built-in 10Gb ethernet which is a lifesaver for your workflow. Dont cheap out on memory either; get G.Skill Trident Z5 Neo 64GB DDR5 6000MHz CL30 because Ryzen 7000 really loves that low latency. For $3000, you can build a monster rig without waiting for 9000 series stock... honestly the performance gains on the new stuff aren't massive enough to justify the wait.

Building on the earlier suggestion, I'd definitely stick to the AMD Ryzen 9 7950X 16-Core Processor instead of the 3D version. Premiere really likes those higher frequencies and the 3D cache is basically useless for timeline scrubbing. Plus, the standard chip is cheaper and usually more stable for a daily work rig. Be careful about your RAM though. I would suggest checking the motherboard QVL list before buying any high-speed kits because DDR5 can be a bit finicky on the AM5 platform. Since you're on a timeline, maybe grab a Noctua NH-D15 CPU Cooler to keep things cool without the risk of an AIO leak. Make sure to get a solid power supply like the Corsair RM1000x 1000W 80 Plus Gold PSU too. You really dont want to cheap out on power when you've got a gig starting in two weeks... honestly, skip the 9000 series for now. The price premium isnt worth the tiny performance bump for professional work right now.
