I recently got started with mining. I'm using nicehash and it couldn't be easier. They have a benchmark as well. Even if you weren't going to use them you can get an idea of what your system/components are capable of hashing out. I'm mining on a 1600x,1070Ti and 980 which nets me ~ 0.0009 BTc/day
Wish they would offer payouts in other coins as slower miners could take a year plus to get a payment out and do not use their wallets they sadly lied to us all about how secure and offline their wallets are.
Going to throw a few more cards on mine this weekend to happy mining
