Thanks AdolfinWolf, I say that because what I'm wondering is if my hardware is running at its most optimal setting or if I could squeeze more out of it by using a different miner or a different coin. I was hoping to really just have someone say "Yep, that's about the best it can do" or "no, you can improve if you change this and this". Free power makes any penny worth it, I agree. I just can't find a good calculator that addresses hardware as outdated as mine.
