Yeah, the good controllers that give good speed are all PCI-X or PCI-e you just cannot get speed with PCI.

I will let you make your own determination of "good speed" here, but the oldest and slowest PCI bus is 32 bits at 33MHz, or 127MB/s. The most common is v2.1 spec, 64 bits at 66MHz, or 400-500MB/s actually measurable at bus limits. So for most users, the disk is going to be a bottleneck first.

It's something to be aware of before writing off bad performance as "slow bus" limitations.
