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.
