Laptop buying advice forum: Dv7t Quad Customized or HP Envy 17 Customized?

Im looking to buy a new laptop here soon, and I have been comparing NUMEROUS laptops. I think ive come down to these two. Why? The hardware that i would be getting is outstanding, especially considering the price. They have a cheap price tag to begin with and i have discounts that help me save loads of money. So heres the specs on both of these computers, can someone please tell me which one is better.
I will be using this for college, and all the fun college stuff that goes with it. I will also be using it for ALOT of internet browsing, periodic video editing, and periodic gaming. I wont be using it as a gaming console replacement, but ill stick 4-6 games on it and play with my friends online.

And just for kicks and giggles, I was also looking into the new MacBook Pro 15". The specs on this dont seem to be all that wonderful, but people also tell me that you dont need jaw dropping specs to run a mac. I personally am not a huge mac fan, but I am at least giving it a shot. Heres the specs for the one that i would get:

Macbook Pro 15:
- i7 2.2 or 2.4? What do you suggest?
- 8GB of 1333mhz RAM
- 750GB 7200rpm Hard Drive
- Super Drive - DVD and CD writer
- High res. Anitglare Display
- Backlit keyboard

I dont know much about macs. If you say that its good, I would like to know why. If you say its bad, what should i do to make it better and compete with the other 2?

The price doesnt concern me as much as reliability and performance will. I want something thats going to run smoothly, and take anything that i throw at it, all while taking care of my every day tasks.

Thanks!
