Yeah, this is what my wife was doing. I'm also doing the reverse: AMD CPU, NVidia GPU. I considered AMD but went NVidia mostly for the PPW on an undervolted 4070. It results in a cool, quiet, low-wattage machine that can handle anything that matters to me, which AMD GPUs still can't match this gen even with the upcoming 7800XT they're trying to compare against the 4070. I'd wait for some PPW analysis before making a choice depending on your needs. There's way more to the analysis than GPU source code or even raw performance that is often overlooked.

Oh,and don't sleep on AMD. Though I don't feel like the AM5 platform is fully baked, Ryzen architecture is rock-solid and I fully recommend using it if your history with Athlon is what's keeping you away. I actively avoided them for the same reason until a friend convinced me otherwise, and I'm so glad I did.
