My Intensity Pro HDMI Capture Card is PCIe 1x Spec, I had it in my 2nd PCIe 16x Slot on my old system as the First 1x Slot was under my 8800 GTS's heatsink, and the 2nd one had another Addon Card in it.
Most Mainboard's 2nd/3rd 16x Slot is really only 4x/8x anyway.
On the Asus P8Z68-V Gen3, the Black x16 Slot is really only 4 Lanes (4x). per the Asus Site/Manual, You should be able to use that slot with no problems.http://www.asus.com/Motherboards/Intel_Socket_1155/P8Z68VGEN3/#specifications
