Not necessarily. Staking Ethereum does require a certain level of computing power, but it is not as intensive as mining. Generally, you can stake Ethereum with a minimum of 32 ETH and a moderately powerful computer should be able to handle it. However, factors such as network congestion and high gas prices can affect the performance of a node, which may require additional computing power. It is recommended that you research the specific Ethereum staking requirements before starting to ensure your computer can handle it.
