simple question - is this possible? I have a 17" PB with 1 gig ram. Its a Rev A PB (1 ghz). I know that their are very few upgrades possible on laptops, and even fewer on apple laptops at that - but i was wondering if it was possible to stick in a faster more powerful video card if i ever come across one? Since im not as tech savy as some of you, who would i get to do this for me? also, what cards are out right now that would work in the powerbook that are better then a 64 mb gforce 4 that comes stock with my machine? oh and how much would such a card cost?
