I have a 670m in my current laptop (its kinda hard to see in my sig because of ms paint). This cannot play all the games of today at max and may even have trouble playing games at all a few years in the future. Could I take the internals of my laptop out (not separate everything, just take the inner parts out of the case and take my current psu and gpu out and put new ones in? Are the psu and gpu blocked by anything and impossible to get out? HAs anyone ever done this before?
