So the Rev 1.1 board has more power for the USB 3.0 ports is that correct?
I can't say that, it's just pure speculation on my part.
Gigabyte don't publish much in the way of details with their motherboard revisions.
Where can I buy the Rev 1.1 in the UK? I can't find it on Amazon or anywhere else.
Motherboard revisions aren't specified in sales spec, just model numbers.
I believe that all Z77x-D3Hs in the sales channel are now the latest rev1.1. boards. I'll confirm that once the new one I've ordered from Amazon turns up next week, if it's old 1.0 stock they can have it back.
