Hi, I'm from Belgium, I have a late 2010 macbook pro (http://puu.sh/12x94) and am starting to have some issues, I wondered if instead of buying a new computer doing some upgrades would prolong my notebooks life. Firstly my mac seems to have slowed down since I upgraded to OSX Lion, also my battery life dropped significantly (7 hours to max 3), my fans make more noise and my screen freezes sometimes. I'm curious if I perform this upgrade, if my mac will run as new, and how long my mac will stay usable: -2x4 gig of corsair mac-certified RAM -Corsair Force 360 GB SSD -Maybe a new battery, if needed -Upgrade to OSX Mountain Lion (complete fresh reinstall, of course) Questions: -Do I have to buy a new battery too or will upgrading to Mountain Lion fix it? (this is a iStatpro screenshot: http://puu.sh/12x7s) -Will my computer run faster or will my processor limit what I can do? -Will cleaning my fans a bit help with the noise/heat of my computer? -Are there better alternative SSD/RAM's I could buy, will the upgrade 'work'? -How long will I be able to keep this computer after the upgrade, and can I recuperate the SSD/RAM when I decide to buy a new computer? And do you think this upgrade is worth it or should I just buy a new mac? It'll only cost me 350 euro's versus 1700 or something I would really really appreciate if someone could help me! If you need anymore stats, screenshots,... just ask!
