Hello
Is there a different between a gpu which get 16 lanes and a gpu which get 8 lanes?
Cause I can't find a mainboard with 3 or 4 PCIe-slots each with 16 lanes.

If it's 16 or 8 PICe lanes doesn't matter at all.

For acemd, it does not matter.

Even 4x doesn't matter for that other protein folding project. 1x is measurably slower though.

The lanes only reduces or increases the amount of data a card can get from the mainboard ...
For GPU-Computing, this data is very low, so this doesn't change anything.

And even for high-end gamin, I think the difference between 8x and 16x isn't not viewable ^^
