How good are these two cards? it would be best if someone can show me a comparison to a Nvidia Desktop graphics card.
well depends if your a gamer, if not doesnt really matter generally the fastest one and the one with 256MB or more video memory. The downside of this is less battery time, but it's the gamer's choice. since it is a notebook you need to think harder is the chipset right for you as you cant change the video card in a laptop
yes, thats what i mean, i pretty much a recreational gamer, i don't want to max out all the settings, probably something that matches up to a 6600 GT or more would do.
