I have a 9600 GT GPU at the moment.
For development purposes, I’d like to purchase a Fermi GPU on top to sit aside the current 9600. However, I don’t want to use both at the same time, but rather each separately so that I can test performance on both of them individually. Obviously, I could physically swap them in and out, but that would be a pain.
So basically, I’m wondering if there’s a ‘software’ switch that would only recognize one of the GPUs at boot time?
