First off, you're making a mistake thinking you'll get any further assistance from anyone here with that attitude. He was being snarky, but you didn't have to reply with such aggression. Many people here are professionals, and you're essentially getting free tech support. To add to that, as much as you think you've learned from your research and investigation, you were wrong (unless you incorrectly listed the specs). Those two computers are essentially the same shit. Neither of them actually have a graphics card, they have an on die graphics unit. It's an APU, basically a CPU with a slightly beefed up integrated GPU. They're not gaming computers at all, unless you consider every computer a gaming computer. Typically, when you refer to a computer as a "gaming" computer, it means it has a dedicated graphics card. Anyway, they have the same APU, so there should be little to no difference hardware wise, differences in motherboard, RAM (provided they're identical in clock and timings), and power supply should have negligible impact on performance. As for why your computer is weaker than your parents computers, check to make sure both your computer and your parents computer are running the same resolution, make sure your CPU temps are below thermal throttle threshold of your particular model, make sure your computer is in performance mode and not power saving mode (windows option), make sure your RAM clockspeed and timings are the same as your parents (Sys RAM has big effect on APU performance as there is no on die GDDR), and lastly make sure you don't have a virus, or see if there are any background processes that are eating up system resources.
