I'm moving to Ryzen platform. These are the parts I'm going to buy soon:
Ryzen 9 7900
ASUS X670E-A
Corsair Dominator 32 GB (2x16 GB) 5200 MHz
RTX 4070

Goals:
Games: DotA 2, Red dead redemption 2, Forza Horizon 5, Warcraft III reforged
(Also, I'm starting to do photography.)

Just looking forward to buying a reliable PSU for this build, preferably Corsair. Right now I've considered something accessible, not sure which one exactly:
MSI MPG A1000G
ASUS ROG THOR 1000P2 PLATINUM II
ASUS ROG LOKI SFX-L 1000W Platinum

Also, I'd be happy to hear about any part choice flaws or improvements or money saving tips, etc.

Much appreciated.

Well, I did see the photography part, so decided to keep the 12 core. 7900X is only a few dollars more at the moment, and even this cheap dual tower cooler is quite effective. You can always set power limits in the BIOS.

Alternative would be the 7800X3D which is very good at gaming and still a decent 8 core processor. It has lower clock speeds though, so not great for long duration CPU number crunching. 7900X has the full clock speeds even more so than the 7900.

PSU is a newer model from Corsair for the new 12-pin PCIe connector. 4070 is quite a light card. This still leaves room for at least a 4080, but not a 4090.

It wouldn't really be cheaper, but you can also get an older model type 4 modular Corsair and purchase the 12-pin power...

It wouldn't really be cheaper, but you can also get an older model type 4 modular Corsair and purchase the 12-pin power cable separately. But for $100 the RM750E is decent choice for a 4070.

As for the motherboard, be sure you need all the features of X670E before paying the premium.
