Actually, you can't say that. AMD card do a much better job of bit coin farming. Personally, I have never used an AMD card. I prefer Nvidia, but it doesn't mean that AMD isn't good. Both cards have their goods and bads, I just like the quality of Nvidia's products. They are always reliable, but with his budget, there is no way he is going to get an Nvidia card, or even a newer generation i7 at that.
