Ok I need a laptop next year for school, I just got some money and I want to know what I should get, I like Tibooks betters cause the feel and look, iBooks just are weird to me. now about Tibooks. I wanted a Ti550 cause the upgraded 16Mb video card, but my friend said to get a G4500 cause those had L3 cache that make them faster but that model has only 8Mb VRAM, then I heard somewhere that Quartz now built into JagWire needs more video memory than 8Mb to run well, so what should I go for?
