Just a couple notes from using this for about a month:I'm not a "competitive gamer" by any stretch, but I've had a little time to run various games with different tech requirements. Coming from an XBox One, it seems blazing fast. I re-downloaded a couple of the same games and everything loads and moves much more quickly than the XBO. Here are a couple notes on my experience so far.- My screen DOES have "light leaks," BUT they are only noticeable when things are letter-boxed to be narrowed than the 16:9 ratio. If there is any edge-to-edge image on the screen I can't see them at all. I did return my first one, since the light leaks were really bad in several places on the top and bottom, but the second one I got was notably better.- If you are coming from a 60 Hz monitor like I was, you'll probably notice a difference even on games that don't (theoretically) go above that. I tested out Hollow Knight, which I played exhaustively on XBO, and it feels like it moves and responds much more crisply on this laptop. It might just be confirmation bias, but it sure feels like it's smoother!- I'm not sure why Acer decided to design this model differently than the PH-317 models (this is the PH-*315*), but if you want to install a HDD/SSD in the empty slot, you'll need to remove the *entire* back of the laptop to do it. Googling "install hard drive on Acer Predator Helios 300" (or some variation of that) will bring up the instructions for the other model wherein you only had to remove a small 2.5" panel from the back.- I haven't noticed a problem with the unit getting hot at all. Granted, I haven't been playing anything terribly processor-intensive, but after several hours of Tekken 7 at maximum graphic settings pushed to a second HD monitor and running Twitch and Steam in the background, it's still cool to the touch. I always keep it on a flat surface where it can "breath," and I have a cheap cooling stand with addition fans that I got off Amazon that I use sometimes.- The fans are a bit loud, or maybe just more noticeable since you're presumably sitting closer to them than on a console/desktop. I never found them terribly distracting, even without headphones.- That said, the internal speakers aren't great. The speakers on my Surface Pro are probably better, and they're nothing to write home about. Even without the fans in play, if audio is important to you, you'll probably want some external speakers or good headphones. I'm no audiophile, but even I noticed this immediately.
