in a freak turn of events i bought an rx480 - i was about to pull the trigger and came upon some reviews showing that hair works sapped a good 10-15fps, and with it off you can get a good 60fps without issue.
i then watched videos of witcher 3 with hairworks on and off and I preferred the aesthetics of hair works turned off.
At the same moment I saw hot deals had a good price, so I just pulled the trigger without thinking much.
Given it was only 177 bucks with tax (new egg deal and I have to pay CA tax), it seemed like a no brainer; if it doesn't work out I will sell it easily for 120 or so, and then I'll just pick up that gtx 1070 in a few months.
