So no need to duplicate this except to write that gaming is unlikely on the Inspiron 15. You didn't reveal which model of the 15 so let's pick on one with a GPU.
This GPU http://www.notebookcheck.net/AMD-Radeon-R7-M270.139590.0.html shows gaming running but all are at low or medium settings. The person that wanted to game might be stressed as they may not know how to set these up to play on low settings.
I'm going with no, the Inspiron is not a good choice for gaming. It should be fine for web and video play.
This is Deepak . I need to buy a laptop .
The main purpose - watch movies in HD, play games (not like hardcore gamer) , but love to play latest released ones like Arkham Night , Mad max etc
And to work on documents, online purpose and the normal usage.
I have considered Alienware which is priced 5K in Malaysia.
While there are other dell laptops like Inspiron 15 5000 Series which is priced at 3700 RM .
So would like to know why so much difference between in price and specs between these as the Inspiron has 4 GB AMD Raedon while Alienware 13 has 2GB Nvidia .
Suggestions needed in case there are other good laptops too .
