Hi, I am so not hardware savvy and may not be asking the right question, but here goes...I need a new computer a.s.a.p. It seems my choices are something with an AMD Quad-Core Processor or either an i3 or i5 processor. I understand one is better for gaming, which is not what I would be using it for. I used it for basic stuff, and lots of music and photos. What can you tell me about these processors? And I see no one really recommends buying a computer from Best Buy, so where do you recommend?
