If the HD 9970 (or whatever R9-2xx) is too close in price/performance to 780, Nvidia can match HD 9970 in price (if in $600 range) and thus win in performance.
AMD's best game would be to be tightly close to 780 in performance and win on lower price. Ideally for AMD, HD9970 would score slightly higher forcing Nvidia to lower price or lose sales - and revenues.I am confident HD 9970 will trash 780 in Open CL, but how much does this weigh in most purchasing decisions have no idea.
On a different note, my understanding is that AMD offers some apps to boost GPU performance when used on an AMD platform - just an impression from reading through AMD website.
7970 GHz still trashes GTX 780 in OpenCL by a huge margin.Source

. My CPU usage is between 1-7%, GPU core usage is 27% max, GPU memory usage is about 350 MB, GPU power consumption is about 30 watts max.
And believe me It is not even using one CPU core out of 8 at full speed. I call that is a hell of GPGPU improvement. Edited by sumitlian - 9/18/13 at 9:07pm
