I am sharing my experierence with lenovo notebook I bought it for 49000 firstly its look impressed me when I opened its packaging then from that day I am using it has mind blowing performance and graphics as I love to play games it runes huge games smoothly and hasnt hanged till now and I am hoping it wont hang in future and it is durable and great experience and has appropriate ram according to my needs it is preloaded with windows 10 but I would suggest to buy it in diwali season most probably you would get lower price than now it is best option for middle class people in market
