NVIDIA GeForce Convert to NVIDIA Quadro

just want to ask if this is possible.
my GTX295 can be converted to quadro fx5800?
because the hardware component are identical.
even the specs it almost identical. (voltage, rate bit, etc)
by flashing the gpu and installing the quadro software/driver.

is this possible?
kasi kung pwede malaking katipiran, just like upgrading without burning bucks.

thanks guy!

they call it softmod (software modification)
anyone here has an experience with that?
thank you!
