@nathanletwory, your description seems to be trivialised. I would say that GPU rendering using cards with GCN1 architecture is a waste of time and energy from now on. Below is a comparison, a simple box and a sphere rendered with CPU:
100 Samples rendered in 23 seconds (CPU)
Now rendered using GPU (AMD HD7970 3GB). During the rendering the GPU load was 95%:
19 Samples rendered in 10 minutes and 7 seconds (GPU)
