Hello all, I have to purchase laptop to work before everything to go with my clients, I have two PC GAMERS Office components Asus ROG, I trust for years to Asus never a problem. If not for the G551JK I find the battery charging too much like I test games like COD BTF4 etc. nothing very little heat resist him before the comment that says there screen problem I have not had to issue. keyboard backlights top to activate FN + F4 or F3 to decrease the intensity. I wanted to take the model with SSD partition 24 Giga much more expensive, but this one with us his DD 7200 rev / min Windows starts snapshot, make a hidden partition backup recovery for my part I do them on a flash drive 16G serving really has that. I'm happy with my purchase I think 749 is better to buy an Asus ROG you know what ............................. ......... I get a star for the battery
