Hi there,
The problem with the longer Graphic cards on this board is that they do cover the SATA ports. I have a Sapphire 4850X2 and when I installed it on this board, it caused all kinds of grief. Even using SATA cables with a Right Angle Head put too much pressure over the SATA Sockets when I tried to install the Graphics card. I did manage it but it is not something I would recommend as it could quite easily cause some severe damage to that area of the Mobo.
