I upgraded my motherboard, CPU, memory, and case within the last six months, and now I want to replace my Radeon RX 6600 with a graphics card that has 16GB of VRAM. The upgrade is mainly for modern gaming and game development. My current system has a Ryzen 7 7700X, Gigabyte B650 Gaming X AX V2 motherboard, 32GB of DDR5-6000 memory, a 1TB PCIe 4.0 NVMe SSD, and a 430W Thermaltake TR2 power supply. I currently play at 1920×1080 and 75Hz on a 21.5-inch monitor. I have not settled on a budget yet, so I'd appreciate advice on which GPU tier makes sense and whether I should upgrade the power supply or monitor at the same time.

If you plan to keep the current 1080p display, something around the RX 9060 XT 16GB level should be plenty for high-refresh gaming. If you want to move to 1440p, a stronger card such as an RX 9070 XT-class model makes more sense, while 4K gaming generally pushes you toward the much more expensive upper-end cards. A faster 144Hz monitor would also make a GPU upgrade easier to appreciate.
Your current power supply should probably be replaced before installing a modern GPU. A quality unit with enough wattage and the correct PCIe connectors will give you more headroom and avoid stressing the system. The right wattage depends on the card you choose, so decide on the GPU and PSU together.
The budget is the biggest missing detail. At 1080p and 75Hz, a high-end card would be heavily overkill, so upgrading the monitor may provide a more noticeable improvement. A midrange 16GB card such as an RX 9060 XT-class model would be a more balanced choice, but check the required power supply carefully.
Some people are recommending cards ranging from midrange 16GB models to flagship hardware, but there is no reason to buy the most expensive option for a 1080p 75Hz monitor. Set a budget, decide whether you want 1080p or 1440p, then choose the fastest card that fits that target rather than buying extra performance you cannot use.
The listed 430W unit is unusual for a system like this, so I’d verify the exact model and its connectors before buying anything. Even if it technically works with a lower-power card, replacing it is the safer upgrade.
