Is This a Good Choice for My First PC Build?

You can get Windows 11 for much cheaper than $120—like around $5! As for the GPU, I wouldn't go for the 5060 Ti; look into used 3080 or 4070 options. If you choose a better cooler, like the Thermalright Phantom Spirit 120 SE, you'll notice a big performance boost. Also, it might help if you edit your post to clarify your budget so we can assist you better!

Here's a build I did in that price range: https://pcpartpicker.com/b/wCJMnQ. I went slightly over budget but I can get 85-90 fps on a 4K monitor almost maxed out. If your goal is 1440p, it should handle it well. I recommend saving a bit for a Ryzen 5 7600, but be careful with the GPUs right now because prices are crazy. Maybe hold out for an RX 9070 XT if you can! Good luck!

I suggest checking out my build for some ideas: https://pcpartpicker.com/list/2gdMrM. Also, consider buying Windows from a third-party seller to save cash! That could help your budget a lot!

Your build should average around 70-80 fps at 1440p depending on the games you choose. Don’t go for Nvidia unless you're really into ray tracing stuff; there are better options out there.

Consider getting a bundle from Newegg to keep costs down. Here's a link: https://www.newegg.com/Product/ComboDealDetails?ItemList=Combo.4777479. Just a heads up, it seems the bundle is no longer available. You might need to wait for the next deal or just stick to your current parts. Also, look into a Montech Air 903 Max case or a Lian Li Lancool 207 instead of the Phanteks. And check out cheaper power supply options like Vetroo.
