For 1440p gaming, I would pick the 7800X3D + 4070 combo any day of the week. The games I play are more likely to be CPU bottlenecked. I don’t care much about current AAA offerings, nor do I play anything competitive or even multiplayer for that matter. I optimize for minimum framerate and cap so that the framerate is stable. Minimizing stuttering is more important to me than minimizing input latency because I don’t play anything fast paced either. It’s also easier to upgrade the GPU later. When it’s time for me to upgrade the CPU, it usually ends up being a complete system rebuild.
