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’m in the same boat trying to build a 2x3090 PC. I’m thinking of going Intel because of the stability. The other issue is finding the right motherboard to support both the physical size of the GPUs and the PCIe 4.0 lanes (both size and if the mobo will fully utilize it) and not to mention the thermals and case/fans considerations.

    Let me know your specs and what you end up going with as I’m figuring this all out as I go.
