gen2 vs gen3

[BaronKiller]

If a gpu with gen3 connectors is connected to a gen 2 board.How bad will it affect the graphic.

Not atall it's the same as running PCI 3.0 at 8x.

You mean Generation 3 PCI-E Connector?

Depending on the GPU, you would probably loose 5 frames at most.

The performance difference will be very minimal and you won't really notice it for a single card configuration.
