Need help picking a gaming laptop – what should I actually focus on?

Hey everyone, I’m planning to buy my first gaming laptop but I’m honestly a bit lost with all the specs and options out there. I’ve looked at a few models but I keep getting confused about what actually matters most for smooth gaming performance. For someone who mainly wants to play modern games without constant lag or overheating issues, what specs should I really be paying attention to? Would appreciate any advice from people who’ve already been through this 👍
