I'm using the proportional payout method, but I wanted to know if there's any way to view what my estimated proportion is. I'm currently using three GTX465s, and I'm going to be building a new rig specifically for mining soon, but until that time, I wanted to see what would be more profitable; pay per share or proportional.
Open your advanced settings page and look if the option for hiding percentage is enabled. If the percentage display is not hidden, you will see your proportion on the account page.
