Would a 780 Bottleneck a PCI-E 3.0 8x slot?

92% of originally intended performance isn't that bad. You could still benefit a lot from a 3-way SLI/Crossfire setup.

It would make a lot more sense to buy a 3rd GPU and a new mobo after that, that the other way around. (considering someone wants 3 GPUs)

I don't know about those numbers (Far Cry 2 being the test means it is pretty old).  I don't think I'd want to run 3x670s with one of them being in a PCIe 2.0 x4 slot that hangs off the PCH.  I'd like to see some current testing, but that's got to have a bigger impact on performance, and more importantly scaling.

My brother has a 670 FTW same as mine. I could snatch it for an hour or two and do some tri-SLI on my P8Z77-V Pro. Results could be interesting! tongue.gif
