Hi B NEGATIVE. I have been informed by Accounts that the refund has been processed, but please note it can take a few days for it to show up in your account.
With regard to the reference design nVidia graphics cards, take a look at the product codes and this will tell you if they are reference design. For example, the GX-280N-ZDD9 is reference design as the 'N' in the product code shows. However, the GX-285X-ZWDA is not as the 'X' indicates. Hope this makes sense.
Here is a link to a page on the Videocardshop showing various GeForce 200 series graphics cards, both reference and non-reference so take a look at the product codes.
