Hi I just recently moved and have become disconnected as far as computer hardware. I want to build my father in law a comptuer and was looking at Fry's, as they usually have good deals on processors. I am an AMD fan (bang for the buck), and I started seeing Sempron deals instead of Athlon XP ones. Can someone tell me if they are any good, and if it they are comparable to Athlon XP or are they more like Duron. Are sempron the next generation? I have two systems right now one based on XP 2500 barton and one XP 2800 barton, and I am very happy with them. Any advise is appreciated.
