I am currently running an Asus P8-Z68 V-Pro Gen 3 motherboard, which supports PCI-E 3.0, as per the manufacturers website.
Since I bought the board I have be running an Intel Core i7 2600k.
Recently, I purchased a Palit GTX 680 Jetstream.
Overall I am very happy with the card, but one minor gripe I am having is that it is not linking at PCI-E 3.0 Speeds.
I have been told that the 2600k does not support PCI-E 3.0 link speeds, and accepted.
However, tonight, I saw this review, which shows a PCI-E AMD Card running on a 2600k @ PCI-E 3.0 link speeds. http://www.pureoverclock.com/Review-detail/sapphire-7970-vapor-x/4/
Could any of you possibly shed some light on the situation, as it is starting to confuse me,
Thanks in advance,

that image shows that the board supports pci-e 3.0 but it is not running at 16x 3.0, i instead it is running at 16x 1.1 speeds
(I have no idea why it is running at 1.1, it should be shows as @x16 2.0 so I think that is an error with GPU-Z
PCIe 3 needs CPU support (and nothing is really making use of the added data rate of 3.0 yet so there is not need to worry about that yet)
PS for that motherboard, if you are using a sealed water cooler such as the Corsair H80, then you will need a side panel fan that can provide direct airflow to the VRM heatsinks on the motherboard, or you will risk a blown VRM when overclocking, or a bad overclock due to the VRM protection kicking in, which throttles the CPU.
