Question about a CPU/multi-GPU pairing

Hi, someone near me is selling their machine with the following:

  • 3 x RTX 2070
  • Intel i3 7100
  • Z270 motherboard

and I don’t know whether that CPU, having only two cores/four threads, can make good use of three graphics cards, or even two. (The guide on Tim Dettmer’s site recommends more threads.) Thanks.

Looks like the z270 board can support 24 pcie lanes, but best cpu i could find? i7 7700k only supports 16.

At 1x8 and 2x4 speed drop will only be a few percent (from memory from chai time datascience podcast interview T Dettmers ).

With the i7 7700k - has only has 4 cores. I suspect that may be the thing you notice most.

If cheap enough you could buy for the GPUs?

Thanks for your reply. The seller seems to have changed their offering and the price right after I posted the question. Maybe they were reading this forum!
