Honestly, if you can't play and/or your amp is worth two pounds of poultry at your local store, there is no reason to go for those extreme mesures.
It's a spec, it speaks to the guitar nerd that some of us are. But you will not hear it unless you change the value of the component, or you start messing with the wiring. The overall quality of the instrument, the playing, the overall chain with the speaker at the front row ; are of much more importance.
