Games are where the dedicated graphics pay off. There is not much payoff for video or photo editing so that's not it.
And for now, for today, both solutions on today's hardware and PC/Apply machines will play DVD, video with the right software. Why I must write that is that XP for example does not come with DVD player software. We can fix that for free with VLC PLAYER.
I have a couple of questions regarding when dedicated graphics are needed and when integrated is enough? I am shopping for a laptop and a desktop for "home users". They will likely only surf the net/email and probably like to watch an occasional dvd movie or one of those online rental movies and also there's the msn news videos and the like. No gaming. Also maybe storing photos and streaming music. I was thinking that I would always need a dedicated card but have read that integrated is enough for the preceding needs. Please let me know which and by the way, if you think I need a dedicated card, please include the size memory for the card as well. Not the main system ram but the dedicated card ram. Also, they will have Vista Home Premium, so does that automatically mean get the minimum system requirements for running that OS and that would therefore take care of any other home use graphics needs?
