biggilly :
I had the palit jetstream,nice card just very very very loud,i sent it back as may ov been faulty,and it wasnt sitting straight in my case probably due to no backplate poor build
The main reason why i sold my Palit Jetstream 970. Same issue with you, the build quality is really poor and it not sitting straight inside my casing. End up optimize for Gigabyte G1 Gaming version. Everything was good and great. Good build quality, nice LED, nice look, OC like a beast any many more.
To answer TS question, if you looking for best performer, Gigabyte G1 970 are your top pick. Just make sure your case are big enough to install this long card. Both Strix and G1 got great cooling though.
