Hello,
Will using a SATA III hard drive and motherboard lead to actually faster work versus SATA II drive and motherboard with the same processor etc? Or is the drive itself slower than the SATA II anyway so it does not really matter?

With a standard mechanical hard drive you won't see any difference at all. There would be a small difference with a very fast SSD but even then I don't think you would notice it.

If your MB has SATA III ports, then use an HDD SATA III or SATA III SSD
newer HDD's and SSD's right now are all SATA III, yeah I agree that is not enough gains in performance but take advantage of the new techonology.

SATA II is 3Gb/s
SATA III is 6Gb/s

SATA II is UP TO 3Gb/s
SATA III is UP TO 6Gb/s

If you have a mechanical drive which can only go to 1Gb/s, you won't see any difference.
