Hello, I'm an aluminium MacBook 2.4ghz owner and I feel that it beechballs a little more regularly than I would like. So my question is how do I make my Mac as fast as possbile. A RAM upgrade is the most obvious thing to do, but I've been told that if I'm not doing anything particularly intensive, so I'm just browsing the net, listening to iTunes etc, then I'm probably not using all the RAM I have now, and therefore an upgrade is pointless. How true is this - if I seldom use the full 2GB of RAM I have now will a 4GB upgrade not give me any noticable speed increase at all? I've also been told that HDD upgrade will make the Mac faster. I've been told to get a 500gb one, as the larger the drive the faster it will be - how true is this? I've been told that I should get a WD Scorpio Blue, have these been known to give performance boosts? Is there any risk of voiding the warranty? Finally, is a 7200rpm HDD plausible for a MacBook? I know a SSD would be the best option, but one with a decent capacity is well out of my price range. So please let me know what I can do to make my Mac faster. Is there any other way to make it faster without upgrading hardware? Thanks.
