Hardware
andCustomizability
Highly customizable
Preferred by many becauseof how easy they can be tocustomize. Because of theway their hardware isdesigned, users can replacegraphics cards, RAM chips,
CD drives, motherboardsand other internal hardwareat their discretion.
Less customizable
Most Mac models, on theother hand, are difficult toupgrade apart from RAMand a few other basiccomponents. Mostchanges require a visit to
an Apple store.

Availability
Widely Available
Windows is much morewidely used, so moresoftware is available forWindows than for Mac. Thisis the reason that manygamers choose Windows,
because many titles aren'tavailable for Mac if the gamedevelopers don't choose tomake a separate version.
Limited
