> The E5 is so good that it lets you do entirely different architectures from what came before it.
As an example: Luke Gorrie is one such person who is actively talking about doing so by talking directly to Ethernet controllers via DMA from user space. Here he is in a 30 minute talk about exploiting 512 Gbit/s of PCIe in his project called Snabb Switch. He's even written a 10 Gbit/s Intel Ethernet driver in Lua. The idea, as far as I can tell, is you can turn a common Xeon server in to a very low latency, zero-copy, multi-gigabit, software defined, layer 2 network appliance.
