A sad sad day at the elemein household... Need fast help please.

The ol' dv6 is dead.

My laptop was a HP Pavilion dv6-3040ca. It was snappy, responsive, powerful, and best of all, it was mine.

It was my first laptop that I had all to myself and that I put my own money into. Though the past few months, it's had a broken hinge support. It has been slowly getting worse and worse, so today I unscrewed the support and the underbody enclosure and opened the laptop a then it happened. The support physically hit the motherboard. Hard. I was surprised it didnt crack. I closed it in my panic becuase I didnt wanna do anymore damage, and it hit it again. Again, I'm surprised it didnt crack, but the damage was done. I tried pressing the power button, and even with a fully charged battery and good AC adapter, it would not turn on. It was recieving power, the only one remaining alive light told me so, but otherwise, it was dead.

I just came back from Best Buy. Got a diagnostic; it was indeed the motherboard. They said it may cost a simple 20$-500$ repair depending on the severity of the damage. They didnt know the severity. I did. I knew it also had a cracked part of the motherboard in the section where the audio unit is housed. And the hinge support mustve done a number.

The dv6. Was dead.

I can not afford 500$ to replace just the motherboard for the hinge support to hurt it again.

I can only buy a new one.

I am a student, so my budget is not very big, keep in mind. I am looking for something that is more powerful than the dv6, so I need suggestions; but I have three main questions.

1. What can I salvage off the laptop and sell to eliviate the costs and perhaps even feel good that parts of my laptop live on?
2. How can I salvage the data off my hard drive? I am 90% sure the hard drive is alive, and I know it's physically A-OK, so how can I extract my data from it?

And the last, and biggest question of all: 3. I have a few hours before stores close. I need a new laptop today or I need to go two weeks without a laptop. I need a laptop during study-for-exam week. So I need a new laptop today. I need a laptop that is:

~14"-15.6" in screen size.
Built in webcam and microphone.
Better processor than Triple Core AMD Phenom II N830 chipset.
Better video card than ATI Mobility Radeon HD 4250 Graphics with 128 MB of VRAM.
Better than 4GB DDR3 RAM. Or equivalent.
Needs atleast 320 GB of HDD space.
Need b/g/n Wi-Connectivity.
Atleast 3 USB ports, atleast 2.0 in version.
Would prefer a 101-key keyboard. I dont need a numpad, but the more standard keys, the better.
Needs Windows 7.

And overall, a good laptop. Can you help me please? I'm desperate for help!

Edit: By the way, the dv6 had one issue. A heating issue. It ran hot and loud often, so a laptop without that issue would be good. Also, If it comes down to HDD speed vs HDD space. I take speed. I only need 320 GB.

My budget is -700$

I mainly play some graphics intensive games, do normal school work (so microsoft office stuff), SOMETIMES edit movies. Very rarely, and dont need a lot of power for it, I do a lot of web surfing (with many tabs), and some other small stuff.

But mainly games (MW3, LoL, WoT, etc.), heavy web surfing (I use Opera browser), and school work.

By the way, IT MUST BE AVAILIBLE IN A STORE. (NO STRICTLY ONLINE PURCHASES)

Thank you very much, and theres been some good news, a friend of mine rearranged something I was going to do tomorrow and I have until tomorrow to go instead, which is good.

My old laptop could do it, but when it came to the games, it ran VERY hot, and I had to do the lowest possible graphics and it was really borderline working. Probably due to the 128 MB Vram which is really quite low... Anything non-games it did just fine though. I'll take a look at what you gave me above and thanks again!

Oh good to know! Thanks a bunch! By the way, I've been looking around at a lot of laptops and theres a few trends I've been seeing.

i3 processors and i5s, as well as Intel 3000 Graphics. Passmark Benchmark says they're all very good, but in practice, how are they actually? Do you have any info on them?

Also, some i5 computers come with integrated graphics, so I assume this would be a "APU"? How are the integrated graphics of the i5 in terms of speed and quality?

Any info on them would be good, Im now seeing that I paid ~750$ for my laptop two years ago, and today I can get a computer that's literally TWICE as good for 600 dollars. Oh technology, you move so fast.
