Probably not a ton of new information for people who are perusing a forum dedicated to Apple hardware, but I know some people were wondering (for instance) exactly what the Afterburner card's limitations were:

Afterburner can be installed in any full-length PCI Express slot in Mac Pro; however, it requires a PCI Express x16 slot to deliver the highest stream counts due to the bandwidth required for decoded video frames. When ordered from Apple with a Mac Pro, it will be preinstalled in the factory in slot 5, a full-length x16 slot. Afterburner is not supported in a Thunderbolt PCI Express expansion chassis and is not supported in Boot Camp under Windows. Afterburner accelerates ProRes and ProRes RAW playback in applications that use Apple’s VideoToolbox APIs, including the latest versions of Final Cut Pro X, Blackmagic DaVinci Resolve, QuickTime Player X, and other media applications. Final Cut Pro X has support for load-balancing ProRes decode, allowing it to take advantage of both Afterburner and CPU cores for enhanced decode performance.

These are a hybrid of marketing and technical papers, so remember to take some of the more outrageous claims with a grain of salt.
