At first I thought it was a monitor issue until I went through 4 of them and finally checked that off as a probable cause.
Tried my onboard Intel 4000 or w/e and again still noticed banding issues on the same places...
The banding was ever so slightly less noticeable, but the refurbished one they sent me the performance was at like 85% of what I was getting with my original new purchase so sent that back.
Ok this is basically proving it's a software issue, you need to quit wasting the various manufacturer's time with RMAs and re-install Windows or install a fresh copy on a different drive.
