Those are previous-gen.
Newer machines would have 6xx-series nvidia GPUs or 7xxx-series AMD GPUs.
The $1100 version isn't too bad as a 570m is about the correct potency for that price, but why buy old hardware when you aren't getting a particularly good deal on it?
If you are going to spend $1700 on a laptop, you should be able to pick up an MSI white-box with an i7 and 680m which will absolutlely bury that 570m.
Try one of the smaller retailers like gentechpc, xoticpc, or powernotebooks.
Here's an example from powernotebooks:http://www.powernotebooks.com/configure.php?special=1367
$1653 credit, $1603 cash (remember to take the $50 discount for orders over $1500)
i7 3610qm (free IC diamond upgrade)
750GB 7200rpm hard disk
Win 7 premium
