I’m looking to build a new PC(which I’ve never done, other than upgrade my current one) for running and fine tuning 7b models. I know I’ll be getting dual 3090 or 4090 GPU, but I’m not sure which CPU would be best for this.

I’m wanting to take advantage of the bundle deals at my local micro center and down to these two options:

  1. AMD Ryzen 9 7900x 4.5ghz 12 core, Asus B650E-F motherboard and 65GB DDR5 for $600
  2. Intel i9 14900k 3.2ghz 24 core, MSI Z790 MAG Tomahawk motherboard and 65gb DDR5 for $800

Anyone know which would be best for my use case? I don’t mind spending the extra $200, I only want the best option of the two

Thanks in advance

      I would say research the CPU/MOBO combo, not just the CPU. In addition: make sure you buy RAM which is on the Mobo manufacturer’s supported list. I have a Ryzen 7 5800 and an MSI MAG B550 TOMAHAWK motherboard. Not gonna lie, I always consider AMD a risk due to chipset related quirks I have experienced with previous builds, but it has been fine so far.
