It's a basic onboard graphics i3 model PC, though certainly better than the Celeron model offered. This is clearly not a 'gaming' system by today's standards, but wasn't looking for one. It does do online HD streaming well though, have multiple subscriptions, don't know about in 4k however. A couple other reviewers were supposedly not happy with 4k results, and the Celeron model was even worse as per reviews, but the Celeron model is only UHD 600 graphics, as compared to newer UHD 630.The Acer support software included is absolutely useless IMO, even for driver updating, seemed to all just hang. Once I registered I got rid of it all (including any left behind folders), sticking to Windows update, as well as free, community-based Snappy Driver Updater for up to date drivers. You can also use the Intel Support Assistant if you like, just download from Intel site, but recommend declining the 'Program Customer Experience' install it wants to do as well. System came with original BIOS flash (there's been two updates since), recommend updating, download from Acer support site, there will be an install.bat within the folder (after unzipping), don't know why they didn't just make it an actual executable for the novice PC user. The system will also come with some third party software, like from Cyberlink, and some cheap games, I got rid of all that as well.Memory installed was actually 3000mhz physically, though system is 2666mhz, found good cheap comparable match elsewhere to add more RAM to the one empty slot, making for 16GB total. Mine's a 1TB hard drive, and the Intel Optane Rapid Storage Technology makes for a faster overall system, though still not as fast as an SSD, but the SSD model was far too much more expensive IMO. The 1TB hard drive comes split in two, the Acer Recovery partition stuck in the middle, that was most certainly dumb, and other reviewers have complained as well. I deleted the Acer Recovery partition to get full, single 1TB drive. There's just no need for a manufacturer recovery partition these days, being you can now just download the OS, create bootable media and install with your Windows key. Note: the Windows' built-in disk management tool will not let you delete the Acer recovery partition, will need any third party option, I used an old free version of EaseUS partition manager. I do loathe the cheaper DVD drives these days, so flimsy, need lotsa TLC when putting a movie or whatever in. I have my system on its side with fan output facing up, makes for easier DVD load. The fan can get noisy at times, if stressing the system. The onboard audio EQ used to be in Control Panel Sound properties, but now need to use the UWP Realtek Audio Console app for EQ adjustment.Well, can't think of much anything else offhand, overall pleased so far, given I got it at a good price. So far a solid PC that's most certainly a lot faster than my old, old PC I had for years before, that had been upgraded to Windows 10, but was not even close to Windows 11 capable, specification-wise. This Acer will need an update to Windows 11, came with Windows 10, 1809 version, which was actually quite an old Windows 10 version. After update to Windows 11, you can get the OS Key afterward to hang onto. I used free Belarc Advisor to find what the Windows 11 Key was, a handy tool to get an inventory of your system. These days though Microsoft already knows your PC is 'Genuine' once you've already installed initially, in case you ever needed to start over with a fresh, clean reinstall.Overall, given the nice price I paid, 4 1/2 stars...unless something changes down the road.
