Pcie lane confusion - quick question

[gr8mohawk]

The board I ordered was ASUS p8z77 v lx
I'm going to be running a 7850 in my PCIE 3 slot at x16
Will using a pcie x1 lane for my wireless card drop the bandwith avaliable to my GPU?
Just because I understand some lanes share bandwith when using two GPUs.

Sorry if a stupid question. Just ordered all my parts and I'm fretting about everything being compatible.

No, the bandwidth to the card will not be reduced.

The PCIe X16 slots' bandwidth are separate from the other PCIe slots on that board.

Some motherboards have two pcie x16 slots. So if you out 1 card in any of the two slots then the slot will offer x16 speeds but as soon as you put a second card in the remaining x16 slot then the speed of both the slots will run at x8 speeds

Good point. And in the case of the OP's ASUS p8z77 v lx, it is even worse. The 2nd PCIe X16 slot is only X4 electrically. So I would advise against wasting money on a 2nd card in the 2nd slot anyway.

OP: Use a single card and you will have full X16 bandwidth.
