Default Maximus IV Extreme-Z Actually DOES Support PCIE 3.0!

I don't think this will be overly relevant as this is a somewhat dated motherboard but I thought I'd share as this is an interesting discovery.

I've been running my i7 3770K on this board for a while now and I've been seeing PCIE 2.0 as my interface in GPU-Z. Recently, I upgraded to a new GPU and tried it in a different PCIE slot (slot 1, which is controlled by the Z68 chipset) and as it just so happens, it's now running in full PCIE 3.0!

This board was never officially stated to support PCIE 3.0 but apparently, with an Ivy Bridge processor it'll do just fine!

Anyhow, just wanted to share in case anyone else around here was using the same board. You might want to reconsider upgrading to a Z77 board!

No reason to upgrade anyway as you won't touch PCI-Ex 2 @ x16 with even a 690 anyway..

I have the Maximums IV extreme Z. Looking at new cpu/mobo for over $500 just to get that pci-e 3.0. I have the R9 290 and although im sure the 2.0 x16 slot is good enough for it alone, im worried i will hinder performance if i try to crossfire. The micro stuttering. I cant stand it. I just upgraded from 6990, where 60fps feels like 30 and so on. Its 'apparently' fixed now, eliminated with the new frame pacing software combined with the new crossfire technology. I have yet to see anywhere online that shows pci-e 2.0 vs 3.0 frame times with corssfired R9 290's. Will 2.0 hinder this? Anyways, how do we know for sure this board runts at pci-e 3.0 ?? Some proof would be great!
