I'd pick the AMD processor. Basically its like this, AMD's processors pack more instructions per clockcycle, therefore do a better job while at a lower frequency. Intel's are speed demons, but while having a higher frequency (3.6ghz), pack less instructions per clockcycle. That AMD processor is way newer than those two Intel cpus so it's more current with the times. It will probably handle anything you want to throw at, so feel free to go for it!
