Well I got through to a nice chap at OCuk and explained the situation, gave my reference number so he could call up the information. He explained that the card has a 3 year warranty (1 and a half still to run on it) but for orders over a year old i should contact the manufacturer, but in the case of ASUS this didn't apply so I'm to send it into OCuk for testing and if they find it the same as I've shown in the screenshots here then they will send it back for repair / replace. If the card cant be replaced then i will get a credit notice or a different card of similar standing (pricewise) from the time i bought the card (around 87quid).
So I'll pop that in the post tomorrow and play the waiting game now

Silly laptop cant do anything compared to my pc
