Graphics Card Drama Update - Replacement for the replacement on the way

So unless I somehow manage to get a third graphics card that dies on me, this should be it ( Yeah I know, I shouldn't be too optimistic ). The retailer was really nice when I chased them up and they finally got back to me and not only offered a replacement and even next day delivery.

The card is already on it's way so if I'm lucky due to the speed I should end up getting it tomorrow and have a brand new card in my computer all free of charge and then I'll have to test everything again to make sure it's all working. It turns out I really dodged a bullet with that card I got because apparently the guy who was testing it was having completely different issues to what I was having so if I had kept that thing it would have gotten even worse. The card wasn't even function right when he tried it and the computer screen was going black and then the whole thing would just restart.
