    PCIX versus AGP

    The new PCI-X slot runs at 16-X in compharison to the 8-X AGP slot, which is great that technology has advanced like that. But, it only runs in Intel machines and it cost more then a over-clocked ati-radeon. Not only that, but there is no software i'm aware of that even needs that much power. So is it even worth buying?

    Getting PCI-X right now is a very bad choice. Wait 6-8 months for the tech to mature and stabailize a little and then buy it. It will be cheaper and have less problems.

    What about PCIe? I've heard that's the way to go these days.
    Is there a sum of an inifinite geometric series? Well, that all depends on what you consider a negligible amount.

    PCIe and PCIX both mean PCI eXpress. It's not the way to go quite yet for the average consumer. Rich guy, yes, normal consumer like most of us here, no.

    1. It does not only run in Intel machines. PCIe is an interconnect standard, and can be employed wherever any manufacturer sees fit (provided they pay licensing fees and such).
    2. There is software *NOW* that requires it, but it's generally in the realm of gaming, and only makes a difference on the higher end cards. *HOWEVER*, a big area where it can have a huge impact is on cards that use shared memory. Integrated video can then access system ram that much faster, and though it keeps latency high, any bit of bandwidth makes a difference to shared video.
    3. It's not JUST for graphics cards. It allows 10Gbps NICs to have a decent amount of bandwidth to the system, and allows for multiple 1Gbps NICs on the bus without oversaturating it.

    This is incorrect. PCIe is PCI-Express, PCI-X is those higher bandwidth PCI slots you see in servers.

    Some searching has showed my error. PCI-X is a standard for pci that is old now and has to do with the 64 channels comm'ing at 133mhz. PCIe is what we're talking about.
