why woul i buy a 680 to put on my sytem single slot in a 8X configuration when i can have a 16 x pcie2 that will probably be faster then 8 x configuration
(we re just speculating here dont dot the i and line the t,imagine this situation for the brand and combo that would be concerned)

I am having quite the difficult time reading your post. In the future, spelling errors, grammatical errors, and lack of punctuation are usually frowned upon.

To answer what I think you are asking, a single PCIe 3.0 card running with a Sandy Bridge E chip + x79, an Ivy Bridge chip + Z77 or Z68 Gen 3 will run at PCI-E 3.0 x16. When running dual cards, it usually shares the lanes, running both cards at 8x. If you are running an 1155 Sandy Bridge chip on your board, you will get PCIe 2.0 x16 speeds with a single card, x8 with dual. You will need Ivy Bridge to get PCIe support with your P8Z68-V board.

Ivy Bridge supports PCI E 3.0, and that comes out in April, from what I have read. You are thinking of Ivy Bridge E that comes out in 2013. I believe Sandy Bridge E supports PCIe 3.0 (x79 motherboards), but someone will correct me if I am wrong, I'm sure.

oh the 1155 will get pcie3 support! it is on the link i supplied.and those chip are on the intel plan for first quater of 2013 release!(unless it will be only avail on 22 nm!if it is then we might have a very long wait in our hand lol)

Is it safe to say that pci-e 3.0 doesn't really matter yet as previous versions have yet to be fully saturated?

OFF TOPIC
Also, correct me if I'm wrong, but it seems like the new gens x8 speed is what the previous versions x16 is. Anyone else notice this trend

there are some Z68 boards that have PCI-E 3.0 support, but all Z77 boards have PCI-E 3.0 support, event he ultra cheap ones. You need a Ivy Bridge CPU to get PCI-E 3.0 support with LGA1155, but if you got LGA2011 it has PCI-E 3.0 support and you would then need a Sandy Bridge-E sCPU, and the platform would need to have a registry key changed to support PCi-E 3.0 on your card.
