I recently have sold my Xbox Series X and I'm looking to build my first budget PC I need a CPU which has 8 core or similar just similar to my Xbox series X for my already purchased Zotac GeForce 3060 ti 8GB GPU (in second hand market). Budget is 10-12k for the CPU.

Usage - Mostly gaming, and browsing/ watching movies.
I'm going to play Competitive shooters and fewer AAA games (less demanding) and would want 60fps minimum and my display is 4k 55"OLED TV if that info helps in anyway?!

Few questions as well-
1)Could you might as well suggest a Motherboard with Wifi and BT and budget also is 10-12k ?
2)RAM am planning it to be 16gb but do I need DDR5 so I don't have to upgrade later? Or DDR4 (8gb *2) should do?
 
Your best bet would be a Ryzen 7 5700 (selling for 13k). If you can extend your budget a bit, the 5700x would be miles better. 5700x's dont come with a cooler, so you might have to fork over a bit more to get the complete package. For either CPU, DDR4 is the only usable RAM standard.
