On my 2600k I only have 16 PCIe 2.0 lanes to allocate to my two video cards, which makes the cards run at x8 mode. With the new Ivy Bridge CPU coming in the Spring I'm looking to possibly upgrade, not because of the increase in CPU performance but just to get the PCIe 3.0 controller to increase my video cards available bandwidth.

Has anyone heard if the 1155 Ivy Bridge CPUs will have more than 16 lanes? Also, has it been announced what the requirements are to use the PCIe 3.0 controller on a standard 1155 board, or if it will even work?

doesn't look like IVB will have any more PCI-e lanes by looking at this chart
http://www.anandtech.com/show/4830/intels-ivy-bridge-architecture-exposed

there are already 6x series boards that support PCI-e 3.0
i am running on a MSI Z68A-GD80 and it has 3.0 support, so the 7x series chipset is not really necessary

You can either be part of the problem or be part of the solution.

Right, I knew there were PCIe 3.0 boards on with socket 1155 out. I was just hoping I could drop in an Ivy Bridge and use the integrated PCIe 3.0 controller so I didn't have to buy a new board. I know it's a long shot.

Thanks for the link, that's what I was trying to find.
