I'm building a PC for my uncle that is a radiologist. Right now we are trying to decide what components are appropriate for his needs as he is on a budget of $1300. The software he uses has a minimum requirement of an i5. He needs a 1TB SSD and a 2TB hard drive and a GPU. My only problem is that we both don't know how much GPU power he needs. I'm thinking something in the 970 range but I don't want to shoot to low and he is willing to raise his budget if he has to get a good computer for his work. I'm also kind of torn on the motherboard as I don't know if I should go on the low end of $70-$100 or go a little higher than that. Any help would be appreciated thanks!
