Nvidia and AMD graphics cards are the best for mining crypto and are usually used to assemble mining rigs to get the desired range of computational power. For example, Nicehash offers a customised 10x NVIDIA RTX 3060 Ti mining rig that punches a decent 600 MH/s with only 1400W. A single RTX 3060 goes for about $399.
