A few suggestions, mine XMR with your CPU and point your GPUs to Zcash or similar altcoin. If facing any complications with setting up, nicehash will be a way to go as it'll help you to understand and cover up the basics.
hmm, nicehash was a great help, thank you for your guide
According to nicehash calculator,Estimate is that you can earn about 2$/day or 60$ month for the two GPU and roughly 8$ on your CPU with their pool.
60 is nothing useful for me, but it may can help my employee, so i helped him prepare the miner for using at nights only.
will update you about the mining stat soon
thnx again
