Hi, I need assistance with all the motherboard expansion terms such as PCI Express x16, PCI Express x4, PCI Express x1 and PCI 2.0 and 2.2. The number of each of these expansion slots differs from motherboard to motherboard. I know a graphic card uses the PCI Express x16 slot. But what is the PCI Express x4 and x1 slot for? How many PCI slots will be considered enough? And what is the difference between PCI 2.0 and 2.2? Last but not least is there a PCI Express x8 slot?
Need assistance

Now I have noticed that the length sizes are different. So does it means that there are gpu made to comply with the x1 and x4 slot?
Most Video card are and need a PCIe X16 slot, theres a few PCIe X1 cards but there not worth getting. Most PCIe 1-4 and 8X slots are for future products

2.2 is a 66 mhz 2.2 volt long card, not used much, As far as PCI slots I would get a board with atleast 2 PCI slots
