This may not be as simple a question as it sounds. I am buying an entertainment/desktop replacement. I game a lot but this laptop won't be a dedicated gamer. I do a lot of audio and video work, plus I require a TV tuner. I am unsure what Nvidia card to get; the 9650 with 1 gig of dedicated memory or the 9600 GT with 512Mb of dedicated memory and up to 2 gigs of shared memory? I had thought I would choose 4 gigs of system memory for Vista 64 bit, however the shared video indecision begs the question of using 8 gigs of system memory? I am hopeful that some of you have solved this question, or at least have opnions. Help Please.
