Probably what i would go with, the whole
reason for getting the second card is that
it's a huge pain in the arse to constantly
pause and unpause folding whenever you
are doing something different.
Then maybe you forget to unpause when
you go to bed, potentially 8 or more hours
wasted until you notice. You don't have to
consider loss of QRB whenever you are
gaming or doing something else, etc..
If you are looking for an alternative to a
dedicated card, you could just leave the
second card folding all the time. Potentially
fold with the first card whenever you feel
like it, that will leave more of an impact on
the power bill though.
