I usually play Garrys Mod and dayz. I use my pc everyday, i stream movies on Netflix, watch livestreams and do my homework so i have to use Microsoft Office.
I'm not a hardcore gamer on pc, i usually play on ps3. So i o not need a pc that is too powerful.
If there are any other gaming laptops that are better and under 1200dollars. Please give me the link.

I've got the Lenovo Ideapas Y510p, and I'm actually writing this right now using it. As far as I can tell by having it almost 7 months it is unfortunately good. Tho the temperatures are getting pretty high sometimes when I'm playing battlefield 4, but it performs very good compared to other gaming laptops. So. I'm from Denmark and we got this company named MM-Vision, which sells gaming laptops with the best of the best: 32gb RAM, 4900MQ processor and gtx 880 for same price range as these laptops. The reason why i didn't buy one of them is because this Lenovo y510p is so damn good. The design fits perfect everywhere and its easy to transportate. Those MM-vision things are pretty heavy and looks terribly, even compared to a ****. So as far as i can tell - I've had all these three laptops in my hands and the Ideapas Y510p is just the best.

I'd say if you're not really into portability, take the Lenovo. But if youre going to bring it around often just get the V3, all of them are fine actually.

Get the Lenovo as it is by far the best
