Spend money and time on what? With regards to PCI, I am pretty sure it will
work. You can ask PCI crowd on the PCI mailing list
(http://www.pcisig.com/developers/technical_support/pci_forum), they will
tell you for sure.And it doesn't have to be a core, you could use an
industry proven silicon, e.g. from PLX. I would be more worried about
processing all this data in your PC. I don't think any PC can do FFT's while
keeping up with such a data flow. Let's say you want to do 1024 point FFT.
At  400 MSPS it will take only 2.56 us to accumulate a new block of data.
The latest and greatest ADI ADSP-TS201S can do a 1024-point complex FFT time
in 16.8 microseconds. I doubt any of the Intel chips can do it faster.
AFAIK, TI DSP's aren't faster either. So, in my opinion you will either need
an array of fast DSP's or some sort of FPGA based processing. Trying to do
this kind of processing in host doesn't sound feasible to me.
