Which Sandy bridge laptop - Hasee

[Nameite]

Hi okes,

I'm planning to buy a new laptop here (I'm in china XD)

And there are two choices in my mind, just need some suggestions to help me choose.

1. Hasee K580P-I7D3

15.6”/Core i7 2630QM 2.0ghz/8G/750G/DVDRW/GT555M 2GDDR3+Intel/USB3.0

R6000

2. Hasee K470P-I7D1
14"/I7-2630QM 2.0ghz/8G/750G/HD6770 1GDDR5/USB3.0

R5800

Which is a better choice? How does the ATI HD6770 with 1GDDR5 mobile compare to the GT555M 2GDDR3?

I do prefer the double gfx option which saves power.

It will be used mainly for some casual gaming~

According to this site the 6770 benches much higher than the GT555M.
