and a x1 card then the mainboard should switch to x16+x1 mode.
Many mainboards allow to set the mode in the BIOS, so you may like to
check. However, depending on you application, the performance increase
is probably very small.
I was curious to see why Im not using x16. My mobo:
ASUS P6T6 WS Revolution

Latest BIOS, checked everything under BIOS settings. I do have currently a single card,
the Quadro 4000, slot 0. I was planning for a second Quadro but Im not sure anymore, probable
I should look at ATI FirePro for future.
