This, for me, is a dealbreaker when it comes to high end SDRs. They do
require top end computers. They also require frequent updates, and
after enough updates even your (currently top end) computer will again
become obsolete. No thanks.

They specifically require DirectX to run the soundcard DSP. I am not
going to spend $250+ for the privilege. Intel needs to write a DSP
routine that runs on Linux.
