I have only read that the hashrates will be about the same so yes, there would be
some tweaking involved. I think that potential resale value would still come into
consideration for a lot of miners though when calculating a break even point.
As long as Sapphire Etc can keep up with the production, it may help everyone
out but I think the jury is still very much out on these cards. It would make me
think twice. Still, some gamers would probably look at ex-mining cards anyway
if they have been modded as I have heard that some games do not like that.
So there is that too.
