What component does this part, which works like the backbone of the computer, connect? How does it provide data flow, for example, between RAM, CPU, and others? What features should you pay attention to so that gaming performance isn't affected?
What exactly does a motherboard do?

Hah, remember the days when I was like "Motherboard? What’s that?" just like you? Makes me laugh 😂 You can install everything else properly, but without a motherboard, all your hardware is useless—just like my exam grades 😅 Talking about gaming performance? At least go for a model with 6-8 PCIe lanes, solid RAM support, and one that doesn’t overheat and shut down, or you’ll end up making a "How fast does my PC shut down?" video 😆
Think of the motherboard not just as the backbone of a PC, but more like the main hub of a kindergarten—connecting everything together. RAM, CPU, GPU, they all plug into this thing, and it’s the motherboard that keeps them all in line, like a traffic cop directing the flow. When the CPU wants to send its calculations to the RAM, it uses the data bus, but if the motherboard doesn’t have enough PCIe lanes or bandwidth, that data flow gets clogged up. I like to call this "traffic jams on the highways," bro, because modern games—especially ones pushing high data loads like the RTX 4000 series—put a ton of strain on the motherboard.
That said, don’t fall into the trap of thinking motherboard quality directly boosts GPU performance. For example, comparing a B650 vs. X670 vs. Z790, you shouldn’t expect a straight-up FPS increase. But here’s the thing: if you slap a 13900K on a cheap motherboard with weak VRMs—like 3+1 phases instead of 6+2—it won’t handle the CPU’s power draw, leading to sudden voltage drops. I’ve seen this happen firsthand as an AMD fan, so trust me when I say VRM quality and cooling are *critical*.
Lastly, one of the biggest factors affecting gaming performance is PCIe version and bandwidth. Running an M.2 NVMe SSD on a motherboard that only supports PCIe 3.0 instead of 4.0? That’s going to slow down load times and even mess with pop-in effects in open-world games like Far Cry. So if you’re thinking, "Eh, my motherboard’s got PCIe 3.0, what’s the big deal?"—bro, those little details will *ruin* your gaming experience.
What generation of Intel/AMD CPUs does the motherboard's CPU socket support? For example, what changes when switching from DDR4 to DDR5, and should I get PCIe 4.0 or 5.0—will the GPU bottleneck otherwise?
Thanks for the question, this is actually the heart of the system so it's a good choice. Check if the motherboard's socket type is compatible with the CPU and if the slots are compatible with the RAM/GPU, make sure to look into that!
