Just don't make the mistake I did and buy a Gigabyte.
Great specs for the price, but I've run in to some nasty driver issues on
Linux (I still can't use my NVIDIA card in Linux whatsoever.)

?Marcus,
I would like to output data that flows from a gnuradio block and RFNoC block
and compare their differences. My assumption is that the gnuradio data will be
all in floating point data FC32 and RFNoC would be generated from SC16 data
which would introduce some quantization noise.
If I were to compare the two outputs visually, I would expect some differences.
Is there a gnuradio block that would display those differences?

The wire format for RFNoC vs regular UHD is the same--16-bit I/Q, and
the gr-uhd/gr-ettus interface converts to floating-point for Gnu Radio
in exactly the same way.
But if you want to compare, assuming the waveforms are mutually
coherent, you could just subtract one from the other, to see the
differences.

If you can get them into the same format(I.e. convert the sc16 to f32 with
a ishort to complex block), you can just add a second output to the
standard frequency sink to see them plotted on the same graph.
