Take those numbers with a shaker of salt. As with all benchmarks
performance depends on the application. Mort's numbers are probably
single precision (I think DP is only supported on the 9XXX series cards
and newer?) and that problem set fit entirely in his card's local
memory. Performance also depends on your GPU's local bandwidth, the
number of shader units (aka "stream processors"), and the shader clock,
all of which can vary quite a bit between cards.

I'm not dismissing GPULIB in any way. Quite the opposite. I think it
is fabulous that Tech-X has made this available and I am quite
disappointed that I am not modeling these days as I would be all over
it. I just wouldn't tell your boss that you can save her tens of
thousands of dollars on that new compute cluster just yet...
