 Stu,

We do not have a 7970 yet. However we do have a 6950 and we benchmarked it and showcased it in our webinar (http://blog.accelereyes.com/blog/2012/02/17/opencl_vs_cuda_webinar_recap/) The opencl libraries from AMD on the 6950 provided about 750GFLOPS for blas which is about the same performance of a gtx 480 with nvidia's cublas libraries.
