My current PC has an MSI B450M Pro-VDH MAX motherboard, a Ryzen 7 5700X3D, a GTX 1660, 16GB of DDR4 memory, and a 450W power supply. I mainly play at 1080p, although I may move to a 1440p monitor later. I recently upgraded from a Ryzen 5 3600 to the 5700X3D, so the graphics card now seems like the biggest limitation. I'm considering replacing the power supply with a 750W model and buying a used RTX 4070 Ti, since new cards are difficult to find locally. My total upgrade budget is around $800, and I'm located in India. Would I need to replace the motherboard for a newer graphics card, or are there more cost-effective upgrade options?

You don’t need to replace the motherboard just to install a newer graphics card. PCIe is backward compatible, so a modern GPU will run in the B450 board’s PCIe slot. You may lose a little performance in some edge cases compared with a newer platform, but it shouldn’t be a major concern. The motherboard only becomes worth replacing if you need newer features such as built-in Wi-Fi, additional M.2 support, or a newer CPU platform.
With an $800 upgrade budget, I’d avoid spending the whole amount on a used 4070 Ti unless the deal is excellent and the card is tested. A reliable 650W or 750W power supply plus a well-priced modern GPU would be a safer plan. For 1080p, an RX 7600 or Arc B580 is more balanced; for 1440p, aim for a stronger card such as an RTX 4070-class model or better. Your 16GB of RAM is still usable, but moving to 32GB later would help with newer games and multitasking.
For the cheapest sensible upgrade, look at a used RX 6600 or a similar low-power card. It would be a huge improvement over the GTX 1660 and can run on a decent 450W supply, assuming the existing unit is good quality. If you want a stronger 1440p setup, consider an RX 7600, Arc B580, RTX 4070, or 4070 Ti depending on local prices. Put the budget into the GPU and power supply first; the CPU and motherboard can stay.
I’m also considering a QHD monitor, so I’d rather buy something that won’t need replacing immediately. The 4070 Ti seems appealing if I can find one at a reasonable used price, but I’ll compare it against newer midrange options.
The GTX 1660 is definitely the part holding this system back now. Your 5700X3D is still an excellent gaming CPU, so I’d focus on the GPU rather than changing platforms. A 4070 Ti would work well for 1440p, but make sure you buy a quality 750W power supply with the correct connectors. For 1080p, though, that card may be more than you need unless you want high refresh rates or plan to move to 1440p soon.
That clears up my main concern. I thought the PCIe version might prevent the newer cards from working, so I’ll focus on comparing GPU prices instead of replacing the board automatically.
