for people that really intend to use properly it i don't think anyone would dare doing so. unless they can get it free but still able to get replacement on top of that after breaking one. btw why need to flash Titan into Quadro (if ever existed)? the performance for the card has been unlock so if they really want quadro like performance and precision maybe they just need to tinker with quadro driver to work with Titanell us, if you had a GTX Titan or GTX 690, would you consider giving this trick a shot?
I don't see it being useful for actual application as the Quadro's have ECC memory for a reason and that is why they cost so much more and anyone using an application that needs the ECC memory is not going to risk the accuracy of the data just to save a few bucks !
No, the reason why they cost (much) more is because companies and freelancers see it worthy to spend through the nose for the added performance gained by the drivers. ECC is a fraction of the added cost and the manufacturer support is irrelevant for most people. The productivity gained from faster rendering jobs is not.Well actually most of the reason why these sort of cards cost more is mainly because of manufacturer support.
