I'm thinking about upgrading my GPU since it's struggling with some recent games. I got a prebuilt CyberPower PC back in middle school, and around five years ago, I upgraded almost everything except the power supply. As a gamer who also streams, I've noticed that my current GPU often maxes out while playing games like Baldur's Gate 3, making it tough to run software like OBS or VTubing tools without lag.
I'm curious about which GPU would be a solid upgrade and whether I need to look at upgrading any other parts of my PC as well. Here's my current build for reference:
- CPU: AMD Ryzen 5 5600G 3.9 GHz 6-Core
- Motherboard: Gigabyte B550M DS3H AC
- RAM: 16 GB DDR4-3200
- Storage: Two 2 TB NVMe SSDs
- Current GPU: PowerColor Fighter Radeon RX 6600
- Power Supply: Gigabyte P450B 450 W
I'm aiming for a GPU that can handle more demanding games without lagging, and I'd like to keep my total upgrade budget under $1000 if possible. Any suggestions would be really appreciated!

When upgrading, you want to know the performance targets based on the games you're playing. For a significant boost, consider GPUs like the RX 6700 or NVIDIA's RTX 3060 Ti, especially if you're targeting better performance at 1440p resolution.
Definitely consider upgrading your power supply! A 450W PSU might struggle with a newer, more powerful GPU. Generally, it's good to aim for a PSU rated at least 80% of the total system's TDP, so going for a 650W from a reliable brand like Corsair would be wise.
Exactly! If you plan to get a beefy GPU, make sure your PSU can handle it. I would also recommend checking benchmarks for the GPU you're thinking about to see how it performs in the games you like.

Yeah, and since you're seeing around 60fps on high settings in games like Baldur's Gate 3, those upgrades should help you maintain better frame rates without having to lower your settings too much.
