Reviews for the Lenovo IdeaPad Z575
Source: Computer Active

Most laptops come fitted with Intel processors and for good reason – they're fast and power efficient. The Ideapad Z575 is the first laptop we've seen in a while to come with an AMD processor instead. The Z575 doesn't have any USB3 ports, but it does have three USB2 ports, one of which doubles as an eSATA connector which is an alternative way of connecting fast external storage. There's plenty of internal storage too with a large 750GB internal hard disk.

Most laptops found under $600 are extremely limited in terms of their functions for graphic. The Lenovo IdeaPad Z575 breaks away from this trend by combining an AMD quad core APU with a dedicated AMD graphics processor to provide a mobile platform that is actually capable of PC gaming albeit at modest detail levels.

AMD Radeon HD 6720G2: Dual Graphics (asymmetrical CrossFire) combination of a dedicated Radeon HD 6650M and a 6620G APU graphics card (e.g. found in the AMD 3400M CPU).
Non demanding games should be playable with these graphics cards.
