The only reason to get a 7900 -/X over a 13700K is power consumption.
And well, yeah, the 13600K is an excellent CPU, but I'd call it mid-range, not budget.
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.
