128 is the easy answer. But, the real answer is, it depends on what you want from your machine. A 128MB card will proform, across the board, better. But it likely will eat more battery life and create more heat, likely causing the fan to go on which eats more battery power and the noise will desturb your tranquility.
Looking for your advice:
Acer Notebook with 64 MB dedicated VDO RAM vs 128 MB integrated VDO RAM.
Which one will be the best please tell me I am a newbie.
