Has anyone tried this on the g2.2xlarge instances? I tried and it looks like the Nvidia drivers aren't the correct ones. I don't know enough about linux to fix that myself, even after some googling. The g2.2xlarge spot instances are less than half the price of the c3.8xlarge ones, so I was just interested in seeing how they compared.
Good question!!! The GRID GPUs are fairly low performance for the price. LasersHurt did a test run of these and got really low PPD numbers, so c3.8xlarge or cc2.8xlarge with BigAdv is the way to go.
