HP laptop build?

[Origin Saint]

Hi again. I know I've been posting a lot on here. First about the Dell XPS 15, then about the MSI GE60 and numerous other odds and inns. And I will apologize in advance for any who get offended by me posting so often and about a variety of things. I'm a up and coming techie I suppose, and I need to get as much info as possible before I go spending money on anything.

Anyway, here's what I need. I need a laptop (no desktops), that has a quad core processor, a graphics card good enough to play WoW and Diablo on Ultra/High settings, at least 6GB of RAM, 500GB HDD and up, at least 1 USB 3.0 port, and HDMI capability. And my maximum budget is $1.25K. I was looking at HP's selection and I found one I love to death.

3rd Gen. Intel i7-3610QM 2.3GHz - 3.3GHz (w/ Turbo)
8GB DDR3 RAM
1TB 5400rpm SATA
NVIDIA GeForce GT 650M 2GB
17.3" 1600x900 LED display
Blu-Ray player + R/W to DVD/CD
Back-lit, full keyboard
HD webcam
2 USB 3.0's, 2 USB 2.0's
9 Cell battery
2 Year warranty
VGA, HDMI video output
7lbs
$1,145 + tax & shipping

I plan to multi-task a TON with whatever laptop I get. I need to be able to edit large file videos in HD, play my 3000 song iTunes library extensively, play games such as Diablo and WoW on Ultra/High, browse the web and watch HD videos and movies. So would this laptop work well for my needs? Please, don't bash HP and tell me to buy a Dell or something else, all I've owned are HP's. Also, I WILL NOT purchase any MacBooks. Thank you for your help and opinions. Looking forward to your replies.

Just like with the HP DV6, you should still upgrade the display if you're going to get the HP DV7 unless you require larger text for eyesight-related reasons.

17.3" 1600x900 displays, like 15.6" 1366x768 displays, make things onscreen large and tend to have poor image quality due to low contrast.

Is this a custom-build? I would go with the stock RAM and hard drive, then upgrade them yourself-- HP generally charges outrageously to up your RAM or drive capacity, and it's cheaper to just buy those separately and install them yourself.
