Eventually, x32 and possibly x64 slots will be realized for PCI-Express, but those probably won’t be seen for a good while. Those slots are likely to be used for highly-demanding graphics cards. For now, desktop users will most likely see x1, x2, and x16 slots along with previous PCI slots on their motherboards.

For those who are looking for an upgrade to their system, PCIe (short for PCI Express) is a great technology to take advantage of. However, if you are looking to have the best possible graphics, there is no reason to splurge on a motherboard just with PCIe as AGP 4x and 8x should provide ample bandwidth for any intensive games you run, including Doom III and the soon-to-be released titles. In other words, pick what motherboard you want, don’t just select one that utilizes PCIe. Presently, PCI and AGP will handle most jobs adequately, but for the future, well, that’s a different story
