Hi there, I notice that my 7950GX2 card is running at PCIE x8 speed intead of x16, i know the card is two cards running together but is running in one slot as one card. whe i bought the card i was told clearly that this card can run at PCIE speed of 16x. I cant find where to change this settings on my motherboard.

Also i wanted to know if anyone knows what Benchmanrking software is better for checking individual components performance so i could descide what to upgrade.
