quick PCI speed question

[clintpatty]

I googled conflicting information on this, so I'm looking for the answer here. Is the max transfer rate of a 32-bit PCI slot 127MB/sec, or is that the max rate of the entire south bridge? TIA, as it's going to help me make a decision about this controller card.

peak transfer rate of 133 MB per second for 32-bit bus width (33.33 MHz × 32 bits ÷ 1 byte/8 bits = 127 MB/s) [1 Megabyte = 2^20]
