I have an HP Pavilion g7 Notebook with an AMD A6 3420m APU. It was originally purchased at Best Buy for 450$ and it had 4 Gb of RAM and 500 Gb of HDD space. since i've had it, I've doubled the Ram to 8 Gb and the HDD space to 1 TB. I went to http://www.gadgetvalue.com/ and put in all the information it asked for and said it was worth about 600$ - 650$ but i wanted a second opinion.
