Asus K53TK bzw. A53TK

[Macgomes12]

Hello everyone,,
I got an offer for an Asus A53TK notebook, which I can get for 400 €.
Since I could not find this model anywhere, I  found  out that the K53TK has the same specifications as the A53TK except for a larger hard drive.

The data:
AMD quad-core A6-3420M
AMD Radeon HD 7670M with 1 GB
RAM 4 GB of RAM
320 GB hard drive
Typical ports + 1x USB 3.0

I'm not sure if I should get this notebook, because I get no experience reports there , I currently have a Lenovo B560 with an Intel core i5 processor and a slightly worse graphics card.

Maybe someone of you know the Asus notebook or the components and can tell me whether a change would be worthwhile?
