4070ti for deep learning training/image processing

I'm going to buy a 4070ti for my deep learning research projects (specially for computer vision). Does it worth the price? Or there's any other alternative? Or should it be better to buy 4080 or any other graphics from the last generation ?
I may need to train for 3-4 days continuously
