The 6gb version is also around 11% stronger ,street guru were I live a 570 costs the same as a 6gb 1060 and is a weaker and hotter card with worse drivers. Rocky I would recomend the 6gb card if it is in your price range but I use a 3gb card and have not had any problems with vram so far but if you are keeping it for more then 2 years it may be a huge benefit down the line.
