I don't think you can find anything good for around 85 dollars, maybe a 2nd hand card, but it's almost impossible with nVidia. The problem is that all the decent cards at this price range are almost nothing compared to the 960, so as I already said, 2nd hand cards are your only reliable choice if you want something more than a hot buzzer in your case. I'd obviously recommend a 2nd hand 960, bt if you really want something new then it's a GT 740 which just might run it on low.
