Does a Gigabyte R9 280 3GB run PCI-e 2.0 and 3.0 or 3.0 only?

Then I guess you'll have to take my word on it or just search the forum for the hundreds of other posts also asking if a 3.0 card will work in a 2.0 slot the answer is always the same, yes.

It will work in a 2.0 slot. However it will not work to its full potential but to the potential of the motherboard. If you plan on upgrading your motherboard at a later point then this will be ok, otherwise it is a waste of money.

A pci-e 2.0 slot is not going to be a bottleneck for a 280. A dual gpu card like a Titan z or the 295x2 would probably be bottlenecked but not a single gpu card like the 280. The performance of a 280 in a 2.0 slot vs a 3.0 slot will be virtually identical.
