Hello,

My current system has an i7-4790 cpu which has 16 pcie lanes. My question is how important is if the pcie lanes will be the bottleneck for the GTX 970? I read that SLI requires at least 8x (so I can have at least 2 cards) but since I don't need SLI for octane, I'm wondering if I can get away with using 4 GTX 970 at 4x PCIe 3.0? The only video I could find online was about FPS in games and it showed that PCIe lanes were not the bottleneck (https://www.youtube.com/watch?v=rctaLgK5stA)

Thanks!

No any difference between PCI-e 2.0 x16 and 3.0 x16 on Octane Render.

Thanks for the replay nuno. But I was not only talking about 2.0 vs 3.0 but about PCI-e lanes that CPU has 4790k has 16 lanes only (only 1 16x card), so If i want to use 4 cards I'll have to use the cards as 4x (0.25 of the bandwidth of 16x)

Thank you.
