I am planning on getting another GTX590 to the farm and
was wondering if the one that i have crunching will benefit from
running 3 instances ?. I run 2 per GPU today. See loads of about
93 to 95%. Is it possible to squeeze out more by running 3 ??

On the GTX570 I run 2 instances.
On a GTX590 I would run 3 instances.

This presumes you have reserved one CPU core for feeding the GPU.

Yes, one core reserved for GPU's

Well done Wizard, looks like you're starting to catch up from the outages and putting down some big time returns now. We can start setting our sights on the #6 team RAC spot again.

I run 4 on my GTX580 and that gives about 90% memory utilization and 95% GPU utilization. Not sure if it's ideal or not but it keeps it maxed out.
