You can get 2x16GB 6000MHz CL30 RAM for under 11k.

I have a 3070 & 3070Ti was never a good GPU IMO for its price, stay away. Get used 3060Ti/3070 under 18k/21k with warranty to save money, if you want. Used 3080 vs 6750XT is your call. 3080 will perform better & DLSS is slightly better than FSR even now, but you have to risk it with a used GPU & live with 10GB VRAM (not as big of an issue as 8GB VRAM in 2024). 8GB VRAM is the minimum you need for gaming now. But at 1080p, 8GB VRAM is totally fine, moreover you can just lower texture quality a bit to reduce VRAM usage. I run FH5 at extreme preset at 1440p but with textures set to high (can't even sustain ultra preset).
I hope you have at least a fast 1TB Gen3 SSD.
You can get AG400 as CPU cooler if you have no plans to upgrade to 7800X3D or its successor in future.
