I have four Core2Duo tower computers that I bought last year for $10 each. Three of them have 8GB of RAM and the other has 4GB. Each one has an Nvidia 1050 or 1060 GPU in it and they run TensorFlow just fine, though the computers are PCIe 2.0, so I'm "only" getting a little over 5 GB/s data transfer between the cards and the CPU. Gigabit ethernet makes that mostly irrelevant.

For the most part, when the GPUs are running all-out on something, the CPU is 75% idle or more.
