Wow, given the data provided, the R9-280X could end up being very close to the TITAN, surpassing it in many areas:

I realized the R9-280X is nothing but an improved HD7970 GHz Edition.
Set the Core Clock to 1265 and Memory Clock to 3470 and you get the right figures -- that seem to surpass TITAN in Memory Bandwidth, FLOP and Pixel Fill Rate. All that while it would get beaten in Texture Fill Rate. How much did they say it was gonna cost? $300 ?
It looks like a done deal to me.
Note the TITAN still has more Texture Units and Raster Operators & Shader Processors. Nevertheless, this R9-280X looks extremely interesting.
