The posters who say that is not the case have gone to the time, trouble and expense of upgrading cables.
You are quite correct I did not go to all this time, trouble and expense. It would also appear to be the case according to a Benchmark Engineer's posts too. I apologise for the sarcasm - it wasn't necessary at all - I should have simply provided the link to Benchmark's own statements about their own product and left it that.
Sorry guys - I owe all all three of you an apology.
