    The PCIe x16 slot is for GPUs, it is the highest bandwidth of them all. I can explain more later, I am in a rush now.

    As JC explains the PCI-E x16 is usually for dedicated graphics cards, the others can be for sound cards, wireless cards, TV tuners, etc.

    Although the PCI-E x 16 slot is usually used for graphics cards, you can also fit PCI-E x 1 or PCI-E x 4 cards too. Since some motherboards have more than one PCI-E x 16 sized slot (though they may run at x 8 or less), you can make use of them for other expansion cards if you aren't running multiple graphics cards.

    A simple "PCI" slot is pretty much worthless today. They are just included for 'legacy' purposes. Pretty much, if you don't know you need a regular PCI slot, then you don't need one. Almost everything has a PCIe alternative now, you'd know if you required a regular PCI.
