Sorry, I so forgot about this, so your bump was great for me.
You did a realy good job... As i had said, you forgot the psu and the mobo was outta stock.

For a mobo cpu.. It comes with a hsf so unless you want a better cooler, you don't really need the Freezer 7. So for the 20 bucks you get a faster dstock speed and a fan.
To me, the psu is very important, I'd recommend a 550W so youre able to slowly upgrade when you want better video cards or powerfuler cpu or more drives.

Is a great psu for the price.
I'd switch the 6670 you choose to this powercolor one as its like 20 bucks cheaper..

As you need windows and a quality gpu this is going to be about $550. You can drop to an x2 and get it down to around $500.

Getting a dual core isnt too bad, as most games won't run more than 2 right now.
I'd recommend getting atleast the 8 series AMD so in a year you will have no issues, i hope, upgrading to better gpu cpus, but it does up the price.
But you can get under $500 if you go with 7 series and the budget brands, like the foxconn and asrock boards
I'm sure if you explain the bit higher now price for a better over time deal, your folks might be more inclined to help.
