Let's say first, it's Awesome product for that money.. Anyone who has doubt whether to buy or not, just go for it, you won't be regret! This mashine will provide hight perfomance in games , sure it's  will depends what you planning to play  but I can throw few examples such a Doom on Ultra preset 160-200 FPS. Shadow of the tomb raider  Ultra preset graphics with turbo mode "on" 76 FPS. To have nice cooling I personal would recomended turn on "Max speed" aeroblade  fans.About screen this is a great IPS matrix but In the dark on a black background you can notice and see Highlights on the screen, but it's nothing wrong with that, it's typical for IPS matrixI had model 2018 Acer Predator Helios 300 based on gtx 1060, and I can say with all my confidence this model 2019 based on gtx 1660 ti, has a lot improvements , and it's very noticeble. Thermal throttling is great,  thanks Acer for undervolting.Battery works good and I didn't noticed any battery drain while battery connected to ACOverall, It's incredible Laptop, Thanks again Acer for that.Of course,  there are as many opinions as there are people and Anyone free to decide.  But I am very happy with my choice
