Upgraded my PC and it is performing worse than before with Premiere Pro

Question

Hi there!

I recently upgraded my mobo and cpu from an Intel i7-7700k to an MSI Z690 pro mobo paired with intel i7-12700k processor. This is leaps ahead of what I was using prior. I even upgraded to water cooler, I have 32GB of RAM, and 24TB of internal storage. Oh and I am using a Geforce 1080 FE from Nvidia. The only things that changed were the cpu, mobo, and cooling.

Now when I am trying to playback just 3 clips on my timeline, the music will playback just fine but the screen remains black. Ill pu the timeline cursor over the clip to see the still image above with the slider and it takes about 60 seconds for the clip to show what I am hovering over on the timeline. Does anyone know why this would be. Everything is pointing to the computer being able to not handle it. I am also editing with 10bit footage from a sony a7siii. I did that with my previous build and it did just fine.

In order to achieve a well-balanced performance configuration for video editing, you need to not just upgrade the CPU and motherboard chipset, but also the GPU. In your particular case the GTX 1080 FE is now starting to bottleneck your new i7-12700K CPU. That is, it will run about as poorly as running your old i7-7700K with only a GeForce GTX 660. The relative performance match between the CPU and the GPU is very important!

Moreover, having a GPU that's underpowered (or too weak) for a given CPU may cause corruption in renders, and possibly exports, when GPU acceleration is utilized because the GPU cannot keep up with the heavy processing demands of certain effects (which again rely on the proper CPU/GPU performance match).
