Will pcie gen 3 cause any bottleneck to 6700xt

[heisenberg 911]

Hey. I need to know if my mobo has pcie gen 3 will it harm the performance of 6700xt at 1080p...

I haven't had any issues in this scenario.

No, it won't. The only cards that are negatively affected are low end cards like the RX 6500 XT, because it only has 4 lanes. For higher end cards it makes very little difference.

 

~edit: not the 6700 XT, but you can see the effect (or lack thereof) on the 6600 XT and the RTX 4090

[bezza...]

will be fine

No, it won't cause a bottleneck. Even if there were a PCIe bandwidth bottleneck, PCIe bandwidth bottlenecks tend to be like maybe 5-10% in the absolute worst case scenario. It's entirely possible to be bottlenecked much more by something like an older CPU rather than PCIe bandwidth itself which is almost never a bottleneck.
