That's right. At least from my experiments with FirePro W7000/5000/4800 cards, it doesn't matter AT ALL if I run them in x16, x8 or x4 slots. Also no impact if I chose Gen3, Gen2 or Gen1. All have the same hash rate in cgminer.
Technically: to my understanding bitcoin mining needs very little info to be pushed to the graphics cards, and then huge calculations are done on this data. The final result is also tiny, so there is very little traffic going in and out.
Those x16 Gen3 Slots are meant to transfer lots of data to/from memory, which seems not relevant here.
