whats the differnts and can you run a pci e 2.0 card in standard pci e slot

Here is a diagram that shows the differences in mobo hardware:

As you can see a PCI-X16 (1.0 - 2.0) card will not fit into a standard PCI-E slot.

A bit of clarification to add - which is that !generally!, you can use a lower level card in a higher level slot. For example, a PCI-Ex4 SCSI adapter will work just fine in an X16 slot - but not vice-versa. The only time I've ever seen this to be not true was with a board specific audio adapter - which actually would only work in one of the two x1 slots
Secondly the difference between 1.0 and 2.0 is bandwidth - the devices will interoperate, but to get 2.0 speeds, both adapter and slot have to be 2.0.

If the question was can you run a PCIe x16 2.0 card in a PCIe x16 1.x slot the answer is yes, you can.

Baldeagl's right, but I will say that there was a time when PCIe 2.0 first came out that many 1.x slots weren't compatible with it. I was doing a lot of reading up at the time and worrying "oh this cand doesn't work in this motherboard" etc etc, but now -- just a short time later -- it seems to be a non-issue anymore. All the hardware has caught up with the new trend.
