Too many different tangents that could be had - starting with the PC/Mac debate.
The keys to best performance are solid state drives (SSDs), lots of RAM and a recent CPU. Most folks don't spend the coin for a top end video card, but should. With all the 3D stuff in Photoshop dependent on it, plus higher resolution monitors now available, the ability to drive a UHD or 4K displays is critical IMHO.
If you do a self build, go for it. But if your day job isn't in IT, go the safe route of buying a pre-built, or make friends with a local computer repair shop to do your build. The computer is a tool, and if you're making good money from photography, dealing with drivers and upgrading components isn't the best use of your time.
