It varies by game, but generally it won't handle 144hz smoothly, let alone reach full saturation on a 3070. (AAA Games) Even at 1440p with maximum GPU usage, the CPU struggles compared to newer models running the same configuration. The 4C8T isn't as powerful as Intel's 4C8T or AMD's 3300X, which puts it slightly behind those options.
It should work well in 1080p, though frame rate might vary in some titles. It's uncertain, but overall it seems acceptable for most videos.
You won't fully benefit from these strong cards with a weaker CPU in most cases. There could be some exceptions, but they’re unlikely. Will the quality reach 1080p144? That depends on the game. Still, it’ll make a noticeable difference if you’re using the iGPU at 3400g or higher (if one exists).
