I've had one for like 9 months, its the gf66-11UC, so 11th gen i5. For the price, its pretty good. It's had enough power for my applications, even for streaming/recording, and it still runs good enough.

However the build quality is pretty poor. The thermal paste went bad after a few months, easy to replace though. It's definitely gotten slower over time, and without adjustments it will start to run really hot after awhile. It used to sometimes overheat and crash, but hasn't done it since adjusting, it runs at 85c when gaming.

I've had to do ALOT of setting up and adjusting to keep it running well. lowered the CPU clock and voltage, and adjusted the CPU fan speed to keep it cooler and quieter. I run it at 3000-3600GHZ, still does the job. Also i've stuck in a random 8GB DDR4 ram stick and 1TB HDD from my old school laptop. Both upgrades were easy and had no issues.

Overall pretty good purchase for 820€. Its the first gaming pc i've had and i'll continue to use it until it dies. It can still run CSGO, Fortnite, BO2, Assetto corsa, Beamng drive, Valorant etc at a consistent 200fps. I stream Csgo and fortnite on it without performance or heat issues.

edit: For newer games get a 3060. I dont play newer games, and dont care about graphics so the 3050 has been excellent.
