Machine is very good , I am also in the decision making phase. 5558 was also almost finalised by me but read a review about its overheat problem and display turn off till heat settle down. Previously it had AMD graphic now they have changed it to Geforce, don't know problem still exist or not. But Allah for bid if you get the problem just shut of for few time and turn on again, problem will be solved , this is what I read in review.
