tttttc :
I never understand why ANYONE will buy the reference design cards.... even for the GTX780, the aftermarket cooler is way better and quieter than the stock fan.
Well, reference card usually has the highest component quality..
That means more durable and has longer life than common 3rd party cards (xfx, zotac, his, polor, and another lowly cheap brand)..
i've still running my 4 years old 5850 reference card..overclocked to 1ghz since out of box, and cooled by mk-13..well, no issue until today, and still rock..
