ok my mac OS X is about 5 years old and it runs SOOO Slow now. it is the family computer so it has a bunch of crap that is downloaded. my mom says we should get the hard drive cleared or something but i think we should start fresh with a new mac. lots of the online games i used to always play never work anymore i just get disconnected. also at my friends house i see them playing on Extrema detail with no lag but with mine on Extremely poor details it lags like a mother. i got a wireless router wich dosnt seem to make any trouble but i relly want to drastically increase the speed of my mac. is it worth it getting it 'tuned or fixed' up? or would it be faster if i bought a new one
