What's the point? With the amount of miners and the current difficulty, you'd barely make anything. If you're paying for power, you'll be at a massive negative offset. Even the 980 ti is pretty much worthless when you're up against people with dozens of RTX 4090s each. It's a lot of work to support something that very few people still have, and isn't anywhere close to worth mining on.
