I havn't herd of any but that doesn't mean there might be one the exist. The only thing I can suggest is gamebooster or Gboost. I think gamebooster charges now and Gboost doesn't.
I will link you to both. It might help or not. I did a lot of reserch on how to speed up your game and what I found out is the PC has to do with how fast your game goes plus getting into your game settings.
So I tried and didn't succeed. But here are the two links. Good luck to you. Oh by the way nice very expensive GPU. I can only dream about a card like that one. I am happy for you.http://gboost.en.softonic.com/http://www.iobit.com/gamebooster.html
