What upgrades should I focus on for my PC build?

I'm looking to upgrade my old PC build since I haven't done anything since 2018. I definitely need a new graphics card, but I'm torn between choosing an AMD or NVIDIA card. My main gaming goal is to run games at 1080p and 60fps. I usually play a mix of indie games and some casual AAA titles. Here's a quick rundown of my current build:

- **CPU:** AMD Ryzen 5 3600 3.6 GHz 6-Core Processor
- **CPU Cooler:** Cooler Master Hyper 212 RGB Black Edition 57.3 CFM
- **Motherboard:** Asus Prime X470-Pro ATX AM4
- **Memory:** Corsair Dominator Platinum RGB 16 GB (2 x 8 GB) DDR4-3200 CL16
- **Storage:** Seagate BarraCuda 2 TB 3.5" 7200 RPM Hard Drive & Samsung 860 Evo 500 GB SSD
- **Video Card:** Gigabyte GV-N105TOC-4GD GeForce GTX 1050 Ti 4 GB
- **Case:** Fractal Design Meshify C ATX
- **Power Supply:** SeaSonic FOCUS Plus 750 Gold 750 W 80+ Gold Certified Seasonal

I'm located in CA, USA, and my budget is flexible between $500 and $800, but I'm not looking for top-tier stuff.
