Guys I have a 3x PCIE x16 Asus P5N-T SLI motherboard that is around 10 years old.

It is PCI express 2.0

If I were to throw (3) GTX 1060's in it would it just be a waste of time? Due to the age of the motherboard?

Would I have a reduced hash rate due to the PCI Express 2.0?

Or do nVidia algos not care about the PCI Express version?

Thanks.
