That right there shows that the intel family integrated graphics wouldn't be strong enough to run that game on a laptop like that due to no graphics power. I'm assuming that screen was 1920x1080 resolution, so it would only be getting 11fps, and anything under 30fps starts to jitter, 11fps would be unbearable.
The AMD a10-4600m I have would run it a bit better, but not as well as you probably want. You can run medium settings with 44 fps, high with 28, and ultra with 20:
With a lot more power, there's this laptop:
It has a 740m graphics card, which runs Diablo 3 at maxiumum settings with a minimum of 46 fps, which is amazing:
My only complaint about this laptop is screen size, being 15.6", cuz i see the other one you posted had the nice 17.3" screen. i'll keep looking. Also, the screen resolution is not usually 1920x1080, but when you customize you can change that for only 50 bucks more, bringing it to 700 bucks.
This card has the same amount of power:
It also has the large screen and nice resolution, along with a strong processor, the only downfall is that I found it on ebay, so those types of things are up to your judgement:
This does come with a 1 year warranty however, which is nice. It is one of the cheapest at 675.
You can also get it through their website for 800
I'm having some trouble finding more laptops around that price that'll run that game that well, so if neither of those interest you at all, just let me know and i'll continue to help. Personally, i'd go for the third one one ebay since it's cheaper, has a warranty, and has all the fancy features I like. If you're not that into screen resolution and size, and want to be safe, the first one's a good bet. Just let me know if I can be of anymore help.
