Which of these laptops are better?

Hey,
I am looking to buy a new laptop, well only reason why because of the free xbox 360 lol.
I want the laptop to be able to play games decently, already got gaming pc
ok so the first laptop is
HP Pavilion dv6t 15.6 inch total price with tax $780
# 2nd generation Intel(R) Dual Core(TM) i5-2410M (2.3 GHz, 3MB L3 Cache) with Turbo Boost up to 2.9GHz
# 1GB GDDR5 Radeon(TM) HD 6490M Graphics [HDMI, VGA]
# 4GB DDR3 System Memory (1 Dimm)

for $75 more i can get 2GB Radeon(TM) HD 6770M GDDR5 Graphics

dell inspiron 15R
2nd Generation Intel® Core™ i5-2410M processor 2.30 GHz with Turbo Boost
6GB3 Dual Channel DDR3 SDRAM at 1333MHz
AMD Radeon™ HD 6470M (64-bit) 512MB (Dual)
total price with shipping 900

does this laptop have two video cards? i am guessing thats what dual means. At first the dell and hp where similar price but stupid dell makes you get a student protection plan and 6 gig of ddr 3 not really looking to spend 900, want to spend around the 700 range.


last laptop is from amazon, so tax free and free shipping

HP Pavilion dv7-4270us 17.3-Inch
# ISION Technology from AMD - Premium with AMD Phenom II Quad-Core Mobile Processor P960
# 4GB DDR3 System Memory (2 DIMM) Max supported = 8GB
# 640GB (5400RPM) Hard Drive (SATA) with HP ProtectSmart Hard Drive Protection
# Genuine Windows 7 Home Premium 64-bit
# AMD Radeon HD 6370 switchable graphics with 512MB DDR3 with up to 2173MB total graphics memory
with blueray player and beats audio
total price $750

which one has best price for performance? I would pick the dv7 but the video card seems to be the worst out of all of them.

or should i wait a month or so to buy a new laptop. Is something new coming out soon? I dont really need one now.
