BSc computer science student seeking new laptop on budget

Hi,

I am new to this website and I am just looking for a bit of advice.

I am a current BSc Computer science student looking for a laptop for use with
graphics programming, programming and gaming. I would like to know if there
are any good laptops with the undermentioned requirements for the undermentioned
price, or if I am being naive in my expectations.

I have a budget of 1000$ - 1200$

Requirements:

17.3' display, full hd
i7 quad core, 2.2+
4/8gb ddr3 memory (with a 16gb max)
500gb+ hdd at 7200rpm
Graphics hard with atleast 1gb dedicated ddr3 (eg AMD Radeon HD 6850M)
Decent battery life. (Not going to be a deal breaker)

Not required:
Blue ray
Good audio
Low weight
Ssd

Sadly over the past few years I've been out of touch with these types of things and desperately need advice.
This is not urgent, just a requirement for next year as my current laptop has reached its point.

Your help will be greatly appreciated,
Regards
James
