Whats up MacRumor! So I have been a Mac user for about 2 months now and just purchased my second used macbook off ebay (because im poor) Im looking to do some upgrading and have questions on both the memory, and HD. here are the specs on what I bought: Blackbook -2.0GHz Intel Core 2 Duo Processor -80GB SATA hard drive -1GB SDARM DDR2 The first think I was going to do was throw a 4GB memory kit in there. Then I read someone suggest that some macbooks will actually support up to 6 gigs. How can I find out if mine will take 6 and if it does, whats the best place to get it? I have been shopping on newegg for years but noone ever suggest them on here. All the suggestions are from mac shops I never herd of. if I can get 6gb of memory to work on this it would be great. Next up is the HD. I was going to throw in WD scorpio (320BG, 7200RMP) But I was curious if this gave off more head then the stock HD? I have never had a 7200 RPM HD in a laptop. I have 2 PC laptop and one gets hot enough to ensure you never have kids if you have it on your lap for more then 5 minutes. the other one does not. I just want to make sure the upgraded HD dosnt get super toasty. Any info would be greatly appreciated!
