You may try Monero, Nimiq or NinjaCoin
I am not certain about the other two cryptocurrencies, but I am very sure monero is better mined with graphics cards like Nvedia, you are not wrong saying it can be mined on computer, there was even a time I read news of HTC mobile phone company specifically building a phone that will be able to mine monero in a way it can be effective like computer, but the best profit to get from monero is to use GPU to mine it which its menoro mining is 30 times or more stronger than that of CPU.
