Intel is technically better, but costs more obviously.
People will come in and say that the fx8### series is better because the 8 cores make it more future proof, but they're wrong, it will still be many years before games start making proper use of more than 4 cores. They mainly only use one or 2 cores today anyways.
And when they DO start making use of 8 cores, your CPU is gonna be a POS by then.
