I think this confirms that the GT 555M on the Y570 is the second version with GDDR5 1506Mhz and 96 cuda cores @ 740Mhz. http://www.nvidia.com/object/product-geforce-gt-55
Concerning the HD 6770M, both cards are comparable in regards to FPS. It's just comes down to personal preference between Radeon/GeForce, price/configuration and availibility. I'd prefer the Radeon becuase you don't deal with Optimus but the HP in not available in Canada besides the Y570/Y470 has a physical switch to turn off Optimus.

so could you please check out the specs and reviews of both y570 and hp dv6t quad/ dv7t and recommend me the better one, based on features and reliability of the two brands....
