It's about time, yes.
I haven't changed my sig, but this past February I went from my i5-4670k to an R5 7600, and the change was noticeable. I'm sure you'll also feel it once you get a new PC.
Please excuse my bad English.
Currently gaming on a PC with an i5-4670k@stock (for now), 16Gb RAM 1600 MHz and a GTX 1070
Steam / Live / NNID : jonxiquet Add me if you want, but I'm a single player gamer.
