im looking to buy a laptop right now and am interested in the acer aspire 3810 timeline. Everything about it seems great except its processing speed is only 1.4 ghz (intel core 2 duo processor su9400). i only plan to use it for word processing, internet, music, videos, etc. I don't plan on gaming. Also i'm currently a mechanical engineering major, but might switch to computer science. Will a 1.4 ghz processor be fast enough for me or should i start looking for a different laptop?
