I've been looking for a macbook with fast speed and big HD. I am looking at 2 online. One is an apple store refurbished Macbook with a 2.4GHz, 2GB ram, and a 250GB HD (http://store.apple.com/us/product/FB467LL/A?mco=MjE0NjI4NQ). I am also looking at an ebay item (http://cgi.ebay.com/Macbook-Aluminu...trkparms=65:12|66:2|39:1|72:2127|293:1|294:50) that has a 2GHz processer, 4GB RAM, and a 320GB HD. Which will run faster? Whick Should I Buy. Help, running out of time
