Radeon Chill Questions?

Has anyone tested out Radeon Chill on the R9 290 or R9 290X GPU Cards

 

With any Game?

 

Or even tested out the Radeon Chill with R9 270 or R9 270X GPU's...

 

 

 

How much better does it improve Game play? Like do you notice any difference at all?

 

In the Speed of your Games? How much Cooler does your GPU get?

 


I have a lot of Games that use Radeon Chill, & am interested in using this for my Games...
