I have had this computer for 4 years now. I have not needed any upgrades and I am able to play AAA high-specs games on at least high setting. E.g. Total Warhammer 2/3. Hogwarts Legacy. Call of Duty. Assasins Creed.Something to note, I had to take out my graphics card and insert it again after 6 months of use. Faulty connection potentially? Everything has worked perfectly since this. (note I did not replace the card just reinserted).Additionally, there are several HDMI ports. Do not use the ones HIGHER up on the device. It links to the motherboard. Plug into the gpu hdmi port, not the motherboard port! This is basic but I didn't realise initially.
