How?
CPU - Your CPU is .8 ghz slower.
GPU - Your GPU is much older. There's not much else to say.
OS - I have Windows 7 Ultimate, you have Home.
RAM - There's a difference between RAM and hard drive space. RAM is short term memory, nothing else. I can't say anything about that because you don't know what you are talking about.
Edit: Assuming you are right about how much RAM you have, congrats. It wasn't a total waste of money.
