There is essentially no way on gods little green planet that you will process 2Gsps on the CPU. You will really need to pre-process within your FPGA framework.

I understand that using the FPGA or the GPU could be quite efficient. BUT, I want the signal processing functions done in the CPU whereby the waveform is processed in GNU Radio (or other C++ implementations). I'm currently looking for a computer that could handle this sample rate. What kind of specs do you think I could look for (RAM, CPU frequency, cache size etc).? What specific products would you recommend?
