The RTX 3090 is a beast compared to what researchers had available to them just a few years ago. Don't try to chase SOTA - that's a fruitless endeavour. 24GB of VRAM is plenty for CV and you can train some excellent models with it. You also need to keep in mind that you don't necessarily need to train models from scratch either. You can achieve great things by downloading a well-tested, pretrained model and fine-tune it for your particular task or application. Trying to come up with new models and training them from scratch is an exercise in futility for really big models. I usually only train smaller models (couple of million parameters) and training and finetuning usually takes anywhere from a few hours to a day or two. But then again my hardware is two generations older than yours.
