It should come as no surprise to anyone that the gaming industry is quite capable of forcefully driving the need for innovation - often found in the form of faster processors, more powerful 3D graphics adapters, and improvements in data exchange protocols. One such specification, PCI Express (PCI-E), was prompted for development when system engineers and integrators acknowledged that the interconnect demands of emerging video, communications, and computing platforms far exceeded the capabilities of traditional parallel buses, such as PCI. Although PCI Express is really nothing more than a general purpose, scalable I/O signaling interconnect, it has quickly become the platform of choice for industry segments that desperately need the high-performance, low latency, scalable bandwidth that it consistently provides. Graphics card makers have been using PCI Express technology for more than a generation now and today's choice of PCI Express-enabled devices is becoming larger by the minute.
