So, before i just had the igpu (vega 8)
I ran 3DMark time spy and the graphics score are 1820, for cpu 3384 and overall i got 1955. I dont even know what these scores mean but i think i was just bellow average(1974)
About the crashes, well it depends.Sometimes it crashes to desktop without any error message, sometimes it does give me an error message (a different one every time) and when i looked it up internet said it has something to do with my graphics card, thats all i know. Btw sometimes i need to restart the whole pc 'cause everything changed to 480p res after the crash.
Yes, im just as confused as you are.
Nothing makes sense
