I'm trying to find the actual GPU processor load on my iMac with the M290x. The load average being reported never goes above 5, even when running Cinebench 3d benchmarks. Certainly that doesn't mean only 5% GPU utilization does it?
How do I interpret the Load Average (i assume that it's the reading for the GPU)? I've attached a screen shot.
Running latest Yosemite.

Load average is CPU based, not GPU based. The numbers represent one, five, and fifteen minute averages of the load on the CPU.

1 core with a load of 1 means that core is 100% busy. But you can add loads when heaving more cores. 4 cpu's with a load of 1 means the total of the 4 cores is 25% busy, a load of 4 means 100%. A load higher than the number of cores means that the cores can not handle the load an the cpu is running 100% per core (and is the bottleneck of your system)
