DAWs are a very specialized application that requires a high performance machine that is stable, and where all the hardware works together without any conflicts with your audio interface and other devices. The wrong choices can lead to random clicks, pops, and other audio glitches, or simply not being able to achieve a low enough latency to work effectively with VST instruments. In the worst cases, hardware conflicts can cause random crashes or freezes, or the system may not even boot up.
