It depends on your graphics card specifications and what resolution you run the game on

Web graphics are not displayed at a higher resolution than 72 or 96 dpi. It is a good idea to design at a higher resolution in case you want a printed piece, then do a 'save as' and reduce the resolution for the web.

Generally higher resolution is better but three are instances where increased resolution makes no difference. Text based programs tend to use a far lower resolution than is available. Increasing resolution does not increase readability. Also, using a very high resolution monitor to display low resolution graphics will not make the graphics any better resolution. As high resolution graphics demand a lot of processing power, unnecessary resolution can sometimes take processing power away from other more important tasks. So, while there is no need to obtain the lowest resolution systems, beware of spending more money on a high resolution display if you simply don't need it.
