Is the Lenovo IdeaPad y510p (Core i5,8gb ram,1tb hdd,2gb nvidia 750m) worth buying?

I've seen many user reviews about it saying that it has *Wi-Fi disconnection issues, *Screen Flickering problems, *SLI problems, *battery drainage issues, *overheating.

I really like this laptop as I'm into gaming and office work. And the specs are awesome, and I WON't BE GETTING A LAPTOP in the NEXT 5 YEARS or so. Thats why i needed something permanent and long Lasting.
I became disapproved by seeing the reviews, but still I look forward to it.

It is a good machine.
