How do I know if what slot I have? PCI - Also annoyingly called 'Conventional PCI' (like there's an unconventional version?). This is good old 32 and 64 bit PCI that you've come to know and love. The PCI spec has been undergoing a significant set of changes over the years to try to keep pace with speed and system advances. One thing you probably haven't noticed (and don't care about unless you're a hardware guy) is a change from 5V signalling to 3.3V. The spec to which vendors are implementing now is PCI V2.2; There are a PCI V2.3 and PCI V3.0 already defined.
Are you asleep yet? PCI-X - The PCI SIG likes to call this 'High performance, backward compatible PCI for the future' which just means that the PCI SIG is not lacking marketing people. PCI-X uses all the same connectors and stuff as 'conventional' PCI.
The transfer speed is indicated by the goofy moniker added to the end, as in 'PCI-X 66' (which supports a 66MHZ clock rate) or 'PCI-X 133' (which supports a 133Mhz clock rate). Because the data is transfered in parallel, either 32 or 64 bits at a time (or even 16 bits at a time, don't ask), this means that PCI-X 133 offers a bandwidth of 1.0GB/second, and PCI-X 533 could offer a bandwidth of 4.3GB/second. That's all theoretical, of course. If anybody ever builds a system that supports PCI-X 533, drop me a line, OK? PCI Express - This is an entirely new bus architecture, previously known by the name '3GIO.' It's got new connectors and everything.
It even defines a new PC Card (PCMCIA) standard called Express Card. How different is PCI Express from stuff that came befor it? Well, for one thing, it performs serial data transfers and it starts with a base transfer rate of 2.5Gb/second. Data is transfered in packets, and effectively routed via a switch. Transfers are bi-directional, so data can flow to and from a device simultaneously.
Since data is switched, more than 1 device can be transfering at the same time. What's even more fun about PCI Express is that cards can utilize as many as 16 transfers in parallel, thus providing (are you ready for this??) up to 8GB/second total throughput (4GB/second in each direction). These parallelized serial transfers are what are referred to as 'PCI Express x8' (pronounced 'by eight', by the way) for 8 parallel bit streams or 'PCI Express x16' for 16 parallel bit streams.
And, here's some cool news: AGP is being replaced with x16 PCI Express connections.
USB Cards for PCI Macs This page was first posted in 1999. It is outdated and will no longer be updated. It is here for historical purposes only, as it predates USB 2.0 by some time. USB PCI 2.0 cards you may want to consider are the, and the. These should all support Macs as far back as the Blue & White Power Mac G3 (and possibly older Macs as well) and Mac OS versions as far back as 8.6. They only provide USB 1.1 speed under Mac OS 8.6 through 9.2.2, and all but the XLR8 provide full USB 2.0 speed with every version of OS X.
These cards let you add USB ports to PCI Power Macs and clones. Specifications are virtually identical: two USB ports, 500 mA power to each port, requires PCI Mac or clone with Mac OS 8.1 or later (8.6 or later recommended for best USB support).

All cards ship with Mac drivers or work with Apple's drivers. In cases where the card doesn't claim Mac compatibility, I am relying on feedback from Mac owners who have installed and use the cards.
