Pay off credit card or personal loan first?

Just found this site and have been reading a lot. I am making a very concerted effort to eliminate close to $50K in debt across 4 credit cards and a personal loan. In March, I expect to come into about $17K in cash. I have one credit card with balance of $16K and I already turned that into a fixed loan. The interest rate is at 9% and the fixed payment is $371/month. I also have a personal loan with about the same balance at 9.9%, and the monthly payment is $831. Would you suggest paying off the personal loan first and then turn around and use the $831 on the credit card? Seems to me that makes the most sense because it frees up the most cash the quickest.

Thanks for any feedback.
