If you were looking for a cryptonight-based calculator that lets you do just that, then maybe you were referring to (
https://cryptunit.com)
Some have reported inconsistencies with how cryptunit reports profitability but i really do like the website because of it's interactivity and the summary statistics charts. Could be really helpful if you are a cryptonight-oriented miner.
Again i'm not looking for profitability charts but overclock charts. Seeing people's hash rate for various algorithm's at various overclocks. Thanks for the replies though!
