is there a difficulty to hash rate ratio?

[domerdel]

With other currencies that have very low difficulty ratings, how does the # of hash rate play into perspective? I'm looking to build a GPU based miner. I'm not building it to get rich quick, but more of a hobby of getting back into building PC's. I want to mine alt coins that have low difficulty, but wondering how the hash rate plays into it.

As the hashrate of the network for a particular coin rises, the difficulty rises to compensate and keep the number of coins mined per time interval, constant.

I assume you meant hashrate as the network hashrate of a coin. Mathematically, the difficulty of a coin is directly proportional to the overall network hash rate. If the difficulty of a coin is very low and the hashrate increases rapidly, the difficulty re-targets after n blocks for most coins, unless they use KGW, DigiShield or another algorithm to re-target the difficulty.
