I have always had a great experience with the OCUK RMA, albeit the first one a little slow as it took just short of two months for my GPUs to be sorted. I mentioned it and got some new ones as a replacement (Both died at the same time!).
But i'm glad you got it sorted out buddy.
I think some clarification in regards to the RMA with OCUK and Superflower could well be in order though, as in who deals etc...
It's been a month since I sent my 980 away, Still waiting on it...
