found @ local store ....

here is the problem , they have almost the same specs , but the graphics card are different , so here's the 1st question:
1.what better 555m or 460m ? im not thinking of overclocking.....

the asus is Refurbished, what does that mean, its not good? , missing parts? , low quality build? ,.....what does Refurbished means here?...

the last question is about cooling , lenovo Y570 have better cooling or asus G73SW ?

finally , tell me you're opinion about these two and if you have better suggestion , feel free to recommend ....

thank you
