what kind of PC it is?

CPU clock may be less important that companion chips and memory speed.

each packet will be

a) transferred from card to memory
b) processed = read and write from/to memory
c) transferred to card from memory.

so memory speed must be HIGHER than 4*routed traffic=4*200=800MB/s
and PCI should give 400MB/s

so you need machine with 2 64-bit PCI busses (or one with 66Mhz/64 bit),
and at least 1GB/s memory speed.

i never seen such fast PC, but new RDRAM P4 may be CLOSE to that.
