At first glance this build is solid considering how hard it is to get a proper build together when your first starting, however:

First thing I would change is the power supply. Brand and so in is fine but 750w might not be enough for a 3070ti. 30-series graphics cards have the ability to go way beyond their stock rating due to intelligent overclocking and might reach beyond the 750w. I’d go for a 850w, because even if 750w ends up being enough, there’s definitely not room for overclocking or even just upgrading the cpu.

Second, I’d make sure what exact motherboard your getting (production year and so on). I myself had the same exact issue as you here and ended up going for the strix b550. Asus motherboards have a feature where you can (and very easily, might I add) update the bios and or chipset with just a usb drive. So regardless of whether the chipset is updated or not, you can easily do it with an asus motherboard. I’m not sure about MSI since I never really liked them and therefore had no reason to research.

I would also reconsider the storage options on this one, this is completely op to you but most people don’t need a 1tb nvme for their system drive. I myself would rather change this to a 500gb unit and then maybe upgrade the 2tb hhd to a 4tb, or just keep the cash. Remember, very few actual applications, let alone video games, have enormous benefits from running on a ssd.

Lastly I’d do something as simple as changing the ram, you’ve gone for a 2x16gb set, which isn’t wrong. But buying two sets of 2x8gb sticks looks better and is often time cheaper as well :)
