In the case of the Fermi-class cards, you're paying for more memory (3 or 6GB vs 1 or 2), stability, tweaked drivers, and (possibly most importantly) error correction. It's really the same argument as for workstation graphics cards - consumer class cards are designed to sacrifice floating-point accuracy for maximum speed, and in some cases, this is unacceptable. That said the 20- series is really freaking expensive. When I got my C1060's, they were ~$1500/per retail; I think the C2070's are nearly twice that.

It seems like Nvidia would have less of an image problem if the Teslas were the same performance and have more RAM and have ECC. (Also, the value of ECC is diminished if a Tesla is over 3x the price of a GeForce, because then you can run three times and vote.)

It's a bit like overclocking your CPU, you can do it, but it's outside of the warranty. In this case the overclockers are the third party board manufacturers that are trying to get an advantage over their competitors that they can paste on the box so that in the store when comparing two boxes the customer will pick theirs. > (Also, the value of ECC is diminished if a Tesla is over 3x the price of a GeForce, because then you can run three times and vote.) That's not really true. The majority of the situations where the Tesla boards are used you'll find multiple boards in one box already. The limiting factor here is how many boards you can pack in to a system, more = better. So if you'd use the 'voting' principle you'd be wasting tons of power, rackspace and host computers in order to offset the price of the ECC, not just the two extra cards.

    In this case the overclockers are the third party board manufacturers that are trying to get an advantage over their competitors I don't think so; most GeForce cards appear to use stock clocks and Nvidia reference PCBs and coolers.
