Very hard to say unless you can find someone that has this hardware with the board you quoted, Intel tend to rarely supply compatibility tables for competitor platforms...... my gut feeling says you should get 3Gb/s but you might be lucky and get the 6Gb/s that it's capable of.
Another thing in your favour is it's Gigabyte, if there's a board out there that might support it...................
I'd be tempted to "Goggle" the two in combination and allocate an hour for reading, you just might find a reference if you use the "Cache" search option.
