msproject251 · May 23, 2016

My current motherboard (gigabyte h81m-h) supports pcie x16 2.0, will I need to up[grade it to get 3.0 for gtx 1080?

No. PCIE is backwards compatible.

Agreed. PCIE is backward compatible and the performance penalty should be minuscule.

Preecher :

Wouldn't pascal need more lanes?

Not so much lanes as bandwidth.

PCIe 2.0 @ x 16 = PCIe 3.0 @ 8x. If they support PCIe 3.0 for SLI on Z170 boards, you are fine.
