This is so much faster & quieter than my previous pc. I do not play games but I do play on-line Poker & this works brilliantly. I did buy a Display Port to HDMI cable for about £5 to connect a second monitor & that works fine. The white DVi cable I had at home did not connect to the second monitor, but I'm not sure if that was down to the cable or the PC, but as the Display Port to HDMI cable arrived today & works fine as I mentioned, that little problem & concern is now over.
I also bought a Samsung 32" 4k monitor for less than £300 to go with this PC, & it gives a so much sharper picture than the one on my old 27" 1080p monitor, so I recommend that.
To finish, I fully recommend this Acer Nitro N50-610 Gaming PC for anyone looking to upgrade.
As for gaming, I can't comment on that, but I'm pretty sure that it would be more than good enough for most people.
