There was a recent thread discussing this - have a look at https://lists.yoctoproject.org/pipermail/yocto/2014-October/021808.html

You need to start by working out what you'll be spending most of your time doing - full image builds, incremental images, single recipes, etc.

My build system has an i7-3820 overclocked to 4.6 GHz with 16 GB RAM and SSDs. It takes about an hour to build an X11 image from scratch (no shared state, source already downloaded). I could reduce the build time to about 25 minutes by upgrading to a new CPU (12 core, 24 threads) for $2700 - once you have your use-case you can do the math to work out what the payback time will be ;-)
