I have 2 7950 cards, actually3 but only 2 in this rig while waiting for an extra riser
anyway 1 got 630kh/s
while the other start also at 630kh/s
but then quickly goes down to 550KH/s or something

to 1 I have a monitor connected, to the other nothing
maybe because there is no monitor attached speed goes down?

I am waiting for some dummy plugs to arrive to test it

any way to see which gpu0 and gpu1 is which card?
