It depends on the speed of the PCI slot. In saying that, you are only trying to transfer 1Gb/s. http://en.wikipedia.org/wiki/PCI_Express Note the thoughts on there about full duplex..
"PCI Express 1.0a In 2003, PCI-SIG introduced PCIe 1.0a, with a data rate of 250 MB/s and a transfer rate of 2.5 GT/s." "PCI Express 2.0 PCI-SIG announced the availability of the PCI Express Base 2.0 specification on 15 January 2007.[9] The PCIe 2.0 standard doubles the per-lane throughput from the PCIe 1.0 standard's 250 MB/s to 500 MB/s. This means a 32-lane PCI connector (x32) can support throughput up to 16 GB/s aggregate. The PCIe 2.0 standard uses a base clock speed of 5.0 GHz, while the first version operates at 2.5 GHz." I can't give you practical advice, but its a good place to start your reading...
