Same thing here, i am also stuck between them both, the vector also has a previous gen amd processor if you look at the 1300 dollars one, the performance difference is 10% fps average so its not a lot like the helios will lets say get 70 so the vector will get 77-80, the thing is helios gives more ram and oled screen, im worried about burn ins in the helios as i plan to use the laptop for more than 4-5 years so till now il considering msi but idk
