Only reason Nvidia is more used for supercomputers, is that given the choice (between CUDA and OpenCL), a lot of universities, research groups, investment bankers etc. use CUDA. Raw OpenCL GPU compute performance, 7970 is faster than a 680.
That's because the current Kepler cards are specifically aimed at the gaming market. Go read Anandtech's review of the 680. He spells out exactly why it sucks at compute.

I really says something when the ati video card is just as fast in gaming, destroys in compute, and is cheaper.

no, it doesn't say much when you look at the underlying hardware and realize AMD's GPU is actually a good deal larger (4313M transistors vs. 3540M, 352mm^2 vs. 294mm^2) yet is only "just as fast". It might be different if it was actually a good deal faster, say averaging 10+%, and still just as dominant in compute while being cheaper. However its only cheaper because its ultimately a less desirable part; if nVidia wanted (or needed) to they could undercut AMD all day long because they have the smaller GPU (more chips per wafer) and less complex memory system (less memory, less expensive PCB)

basically the roles have reversed in that AMD created a larger, more versatile chip - while nVidia created the smaller, more gaming-efficient chip for this generation...a role reversal we've never really seen before
