This is a Series 3, comes in a plastic body with no graphics card, a low-end notebook.
It's not really a low-end notebook... any laptop is pretty capable with an i7.
Yes, it is a "budget" i7 configuration, but that doesn't mean it isn't powerful.
Ideally, we'd all like to have 1080p screens and discrete graphics cards, but pre-built systems don't usually have that unless you're spending $750+.
Is this an outstanding price? No, but it's not a bad deal and it is a Samsung, so I'm sure the display is pretty nice.
Of course, this deal
might be better for some gamers... because of the dedicated graphics card.
The Lenovo laptop does come with less memory (6 GB) and a smaller hard drive (750 GB), so it is a trade-off. However, the graphics card is not upgradable, whereas storage and memory can be changed later on.
