Man the PCIe 3.0 frenzy is driving me NUTS! The PCIe 3.0 offers and will offer (0) zero benefits until: 1. File-13/eBay SB CPU, 2. File-13/eBay PCIe 2.x GPU(s), 3. Five maybe even longer years before the 'current' GPU(s) can touch the PCIe 2.x x16 lanes.
P8Z68-Deluxe/GEN3, P8Z68-V Pro/GEN3 and P8Z68-V/GEN3
These are ALL LGA 1155 Z68 MOBO's with some half-a$$ PCIe 3.0 GPU switch chipset to the GPU <=> CPU lanes only. Yes, the current Sandy Bridge and forthcoming Ivy Bridge BOTH use the LGA 1155 slot. If the goal is to achieve PCIe 3.0 'performance' gains then wait until the BOTH the Ivy Bridge and NEW Chipsets this coming Spring 2012.
The benefits to the PCIe 3.0 are going to be mainly for the current 'shared' USB/add-on SATA/etc and not the GPUs!
