If you have GPU's still chugging away at non-ASIC algorithms, you are in luck! Nicehash has released an updated version of their miner 184.108.40.206, which includes software tweaks for additional hashrates.
Our 4GPU test rig was running an average of 798 sols/s on the equihash algorithm with Nicehash Miner 220.127.116.11, and after an easy upgrade to 18.104.22.168, we are now averaging 843 sols/s on the same rig. Not a bad increase for little to no work!
