How much fps increase Windows 8 on BF4

[Undeaddude43]

This is my build http://pcpartpicker.com/p/Xcvkgs

I already have windows 7 64bit, how much fps increase will windows 8 supply? Would that increase be worth the $90 to upgrade?

Thanks

You will only got like 6-11ish more fps on windows 8 its not worth the price just for a few fps.

Windows 7

52 min 78 ave 120 max

Windows 8

61 min 88 ave 126 max
