You might wanna try Verium. It's CPU only and GPUs can't be used to mine this coin. The only problem is the minimum withdrawal on pools. You may have to wait for months before you receive your first payment unless you have a CPU farm. You can also Solo mine Verium but it seems the difficulty is a little too much.
As others said, Cryptonight is one of the best algos for CPU mining as GPUs do not have too much advantage over decent CPUs, especially the AMD ones. Look for Cryptonote coins with less network hashrate and mine them.
where can i find those coins? can you teach me , i am a newbie ,thank you very much
