Yes agreed, I have the reference galaxy gtx 570, (galaxy owns kfa2 by the way), and i got up to 870/2300@1.1v for 3DMark 11. Am I just very lucky or why does my reference card beat a card with a custom pcb and cooler?

What I really came to this thread for was to ask about the noise levels to anyone who has heard both the kfa2 and the reference gtx 570.

Hmm well after all that i just went and bought one
Interestingly enough the kfa2 card is about an inch shorter then the reference card. with my quick preliminary testing i got to the same core but slightly lower on the memory (870/2250@1.1) by default the kfa2 is also slightly undervolted (963 vs standard 1038 mV)
The kfa2 card is not allot louder, fan is a little bit whiny though. both cards are next to each other though so of course things get hot and loud. ill try and shift them around later.

EDIT: If anyone would like me to do a more comprehensive comparison just say so and i will see what i can do.
