My only worry is they don't seem to have very many PCIe lanes. But they're cheap enough that you might be able to get a motherboard that supports multiple CPUs,

My only worry is they don't seem to have very many PCIe lanes. But they're cheap enough that you might be able to get a motherboard that supports multiple CPUs, and still save money compared to going 1 high-end Intel CPU. And it might perform better too, if the workload has mixed computation & IO. Web development like the article mentions is probably the perfect fit there. Analytics is probably good too(R, Python, SQL). Careful if you need a video card in there, though.
