Nope. SB/SB-E recently have beta drivers for GEN3 (3.0)
Nope. Sandy Bridge CPU's do not support PCIe 3.0 (they dont have a PCIe 3.0 controller).
Correct, Sandy Bridge-E & Ivy-Bridge CPU's do.
Since the PCIe controller are in-built to the CPU, if the motherboard has the physical electrical lanes that are capable of PCIe 3.0 (like the P8Z68-VGEN3 etc) an Ivy-bridge CPU would be needed In this particular motherboard, ONLY
socket 1155 Ivy-Bridge CPU's will enable PCIe 3.0. Sandy Bridge-E CPU's are socket 2011 ONLY. The P8Z68-VGEN3 will not support it as it is a socket 1155 ONLY motherboard.
No beta drivers will enable PCIe 3.0 if the CPU & motherboard do not have the physical hardware controller/linkages present to enable it and are not paired correctly. =) The beta drivers you mentioned were for the x79 motherboards I think (not exactly sure)
