I've been out of the mining game for a while and I'm considering getting back into it. I'm looking at getting a high-end desktop computer with a single powerful GPU (https://fenn.systems/build/njord-maxx/ with i9 & 4090).

Given the advancements in mining technology and the increasing difficulty of mining, is it still feasible to mine Bitcoin in 2024 with just this setup? How does this compare to miners with multiple GPUs? Are there any significant differences in profitability or efficiency?
