Okay, so just recently started having this problem no matter how long it runs the website never says anything over 20 KH/s. I'm running one sapphire 7850 2GB OC edition. I tried changing the intensity but from low to high makes no difference on the payout. I'm making almost nothing now was making roughly $1.50 worth coins a day. I've also tried at least 10 different mining pools. Please I could really use the help, thanks

Here's what things are looking like:
