As the titel says, just have got my 2nd 7970 home. And it has a blue / green pcb. But all the holls and all that is right, but cant use the card whit that colour in a Black and Copper theme build :/
You should be within a 30 Day return policy if you just bought it, and if your planning on Watercooling it then just get a black backplate and either a black or copper GPU full cover block.
