Four 1080 ti will get you the performance of a single 3090 if you are not using mixed precision. Once tensor cores are enabled, difference is night and day. Training and inference, a single 3090 will blow your multi GPU rig out of the water. On top of that, you'll need a motherboard plus a CPU with lots of PCIE lanes, and those ain't cheap. Pro grade stuff with enough lanes will be north of 10k. Not worth it.
