I'm using an Intel i7 2600K system from 2011 as my main computer because it runs so smoothly. I have no plugins or software that requires any online connection (I don't even have a network card installed) and my 2005 32-bit DAW (Nuendo/Cubase) is set up exactly how I want it. Newer versions are simply inferior to me for daily work. I'm also relying on so many useful plugins that will not run on a 64-bit system. As such I have to do regular backups of the hard drives as well as having spare components at hand that works as a direct swap if problems occur. That's really the true risk of running an old system like this. Spare components.
