I have been using AMD since 1999, then changed to AMD Athlon 64 on 2004 and I can tell you, it works stable and fine. No matter what I thrown in its face, it handles the job pretty well done.
My friends had all sorts of problem with the Intel. By the way, paying so much more but getting just extra 20% of performance or saving just a few seconds of video encodings versus a little bit slower but MUCH LOWER PRICE? I choose the latter. Because it just ain't worth it after you pay for hundreds and after 4 years zoomed by, you realized how silly you are, and how you can do better with that same amount of money.
