I'm going to mainly use this for school and some 3d moddeling (nothing to intensive as long as i can play the original crysis at low at 40+ fps its good at 720 p of course) and some rendering but mainly on my desktop this is one off these on the go laptops.
anyways thanks for you help
 


Well then the final factor will be looking at a lot off reviews Thanks for the help eliminating a couple off them.
 


These are actually as good as new and if i want to i can put them in warranty and have it as good as new back in like a week (That store does it fast not intime they warn you or give you another new one if you won't mind)
