What’s the best GPU for i5‑12600K build on a 15 k–20 k PHP budget for gaming/light editing?

Hey I’m hoping to get some advice. The specs of my current build:

- CPU: Intel Core i5‑12600K

- Motherboard: ASUS TUF B660M‑PLUS WIFI D4

- RAM: 16 GB (2×8 GB DDR4 3200)

- PSU : 750w gold FM

- Storage: NVMe SSD + extra SSD

- Case: white — but I might switch to a black case soon

What I’ll use the system for: gaming and light video/photo editing

Budget for GPU: around **₱15,000–₱20,000**

Given that budget and use case, I’m looking for the *best GPU I can get without overpaying* — preferably something that runs modern games well at 1080p, and handles light editing smoothly.

Would you recommend going for something new around that price range, or should I consider used GPUs?

If going new, which GPUs would you pick?

Thanks in advance 🙏
