Below is 1 of the few GTX 780 currently available. Got it 2 days ago.
The exceptional build quality of the card alone sets itself far apart from other existing gpu. Other than the plexi see through glass, everything is made out of aluminium. The fan can spin @ 4000rpm but hardly noticeable. I have noisy cpu fans which probably makes it inaudible.
As per many reviews and my observation for the last 2 days, the reference cooling design is performing at its' finest and it'll be very hard for any non reference design to even compete without increasing the price which is already quite high.
Personally I think this is ONE drop dead sexy looking GTX 780!
For obvious reason, I'm not into any kind of performance tweaking right now but I'm looking forward to tweaks and suggestion as to the usage of other useful features from users who are using 7 series nvidia cards.
