Hello, I believe this is my first post and since I can't post else where I thought I would just post it here.
The first card is;
http://shop.amd.com/us/All/Detail/GraphicCard/11221-00-20GI believe this is giving around 750 KH/s per card.
But the second card is this:
http://shop.amd.com/us/All/Detail/GraphicCard/11221-00-25GAs you can see the only thing that changed was the 20-25.
What is the difference and which one is the best to buy?
