Continuous data streaming to & from PC

Hi,
New to RP and was looking for some hints on this project.
I'm wanting to continuously stream data from PC to both fast DACs and at the same time stream data from both ADCs to the PC. Processing of data is handled on the PC in both cases and the data rate would be 100ksps both ways.
Has something like this been done before that I can refer to ?
Would it be best to connect via USB or Ethernet to the PC ?
Will this involve changing the FPGA or can SCPI handle this ? ...I think not.
Could someone with experience with RP make some general suggestions as to the best direction for me to start investigating ?
Thanks for any suggestions.

It can be done with the SDR transceiver application:

Here are some examples of the PC side code:

Ethernet
