Seeking opinion of Dell Inspiron 7520

[inp3dance]

Hi everyone,

I'm planning to but a Dell Inspiron 7520-148282 notebook with the following specification:

CPU Intel Core i5, 2.5Ghz
8Gb DDR3 Ram
1Tb 5400 RPM HDD
FullHD display
AMD Radeon HD 7330M 2Gb + Intel HD 4000 graphics (switchable, at least that's what I read on net)
Comes with Linux (probably Ubuntu)

If somebody has experience with this notebook, please share with me. My biggest concern is the graphics card, I have no experience with AMD gpus. nor with switchable graphics.

For those interested, here is the link with some more details, however in Hungarian
