Need Advice for My First Gaming PC Build

Your power supply is fine for now and should handle everything without issues. Both the 4070 Super and 5070 perform similarly, so you can choose based on availability or preference since the price is comparable.

While 750W is enough for your current build, an 850W power supply would give you more headroom for future upgrades. Also, investing in faster RAM (like 6000MHz CL30) would be a smart move to optimize performance.

I suggest looking for a 144Hz 2K monitor instead of going for 4K. Most setups struggle with 4K gaming natively, and unless you’re using a really large monitor, like a 36" screen, it’s often not worth it.

6000MHz CL30 RAM is definitely the way to go for your CPU. A 750W PSU should be sufficient unless you choose a high-end GPU, then maybe think about an 850W one.

If you’re aiming for 4K gaming, you might want to consider upgrading to a 7600X and getting a more powerful GPU. For 2K, the 5070 should work fine, but 4K can be a lot to ask from that setup. The RAM you chose is on the slower side; I’d recommend looking for a 6000MHz CL30 kit, it won’t cost much more and can really help your performance.

Dude, this build looks awesome! You're probably going to exceed 60 fps easily with this setup. Good luck with the build!

Consider stretching your budget to a 5070 Ti for better VRAM and smoother 4K performance at 60fps. Also, be mindful that a 1TB SSD might fill up quickly, so plan accordingly. Everything else looks solid though!
