Should I get a Radeon RX 7900 XT/X or Nvidia 3090 for deep learning personal projects?

I am a data science undergrad student looking to specialize in artificial intelligence and deep learning. Right now I'm currently looking for a GPU capable of doing deep learning and computer vision work via PyTorch for personal projects. I am well-aware that Nvidia gpus are generally regarded as the best option for deep learning. Which is why I've had my eyes set on an Nvidia RTX 3090.

However, I saw that RDNA3 cards recently got support for PyTorch with ROCM …
