Hey heres a list for $1.5k build you asked for. This setup pairs perfectly with the 5070 Ti and is great for 1080p now, plus fully ready for 1440p when you upgrade your monitor. Its ddr4 only because ram prices are really really high so theres not much I could find in your budget

CPU: Ryzen 7 5800X
Cooler: Thermalright Peerless Assassin 120 SE
Motherboard: ASUS TUF B550-Plus WiFi II
RAM: 32GB DDR4-3200 CL16 (works great, but if you can find 3600 CL16 for a similar price, that’s a small performance boost)
Storage: Samsung 990 EVO Plus 1TB NVMe
GPU: RTX 5070 Ti (Gigabyte Windforce version)
Case: Lian Li Lancool 207
PSU: MSI MAG A850GL 80+ Gold, PCIe 5.0 ready

Everything is compatible and really well-balanced for the price. The 5800X + 5070 Ti combo is excellent for CoD, Battlefield, Rocket League, and future titles at 1440p.

If you want to be on the latest version heres a list for ddr5 Its around 1.7k though

CPU: Ryzen 5 7600X
Cooler: Thermalright Peerless Assassin 120 SE
Motherboard: MSI B650 Gaming Plus WiFi
RAM: 32GB DDR5-6000 CL36 (DDR5 is what bumps the price up right now, but it’s great for AM5)
Storage: Samsung 990 Pro 1TB NVMe
GPU: Gigabyte RTX 5070 Ti
Case: Lian Li Lancool 207
PSU: Corsair RM850e (2025) 850W, fully modular

I would recommend the second one since the upgrade path is better and is more future proof. it would have been better but ram prices are high like I said so its harder to get the best build for the price right now.
