well that's pretty decent of you, thanks!
the problem is that on the back port the plate is 3 slots with air holes through, it uses 3 screws! tbh I really need to see these boards and take measurements because I think itll be tight with spacing as well as the psu. that's why im trying to find at least one person with similar set up. (the card actually is 3 slots but heatsink 2.5)
EDIT: ive got an idea......thanks to jihad.. ill look at that crossfire set ups mobo manual (above) and try figure it out
looks to me a winner
