> I saw some benchmarks years ago where running a high end GPU at x8 or even x4 had pretty minimal impact. With high res textures coming in for 4K now I'd be curious to see someone run that again.
The average impact is low, but frametime consistency is generally deteriorated much more strongly than the small reduction (0-5 %) of average FPS suggests. That is probably mostly due to blocking uploads, where having a multitude more bandwidth reduces the blocking time. The average reduction is probably more caused by the general area of latency, since modern renderers tend to do a bunch of queries and while they obviously try to avoid it they'll have some amount of blocking commands in each frame frame.
