Unless you know what you are doing, in which case you wouldn't be asking, solo mining something like ETH is not recommended. On a coin like ETH you could be mining fo a long time with no guarantee if or when you will solve a block to receive a payout. Besides hashrate there are a lot of variables involved in solo mining. Things like latency, stratum optimization and block scan time are important factors in solo mining. Large ETH pools are highly optimized and therefore you will generally have the best result and it's not worth the risk to solo mine just to save on pool fees. Another option is to mine on a pool like ethpool .orgwhere you solo mine and receive credits towards receiving a full block reward once you reach the top of the list.
