This really depends on your workload and how much you value latency vs. throughput. If you tend to have a lot of very simple queries, more cores => more throughput, and it may not matter much if your queries take 20ms or 30ms if you can be doing a dozen or two more of them concurrently in an AMD system than in an Intel one. On the other hand, if you have less clients, or more latency-sensitive clients, then fewer-but-faster cores is usually a win.
Either way, the amount of power you can get for your money is pretty impressive.
