Alex is thinking about getting an AMD processor because they seem more affordable. Leo says they are, but really not enough to justify the performance gap. Also, Broadwell processors aren't out yet, but they will certainly be even faster. Leo likes that AMD is out because it keeps Intel honest, and pushes Intel to keep innovating, keeping prices down. That's what competition is for. But sadly, AMD is just not as fast.
Leo recommends consulting PCper.com to research the components for building his own PC.
