Difference between different graphic card iterations?

[Bunke]

So ive been looking for a new Graphics card and i have settled to buy a 1060 with 6GB but i have noticed huge price differences between different models but besides a bit of clock speed (nothing too major in the 20-50mhz ranges which one could easily do with MSI Afterburner) what is the difference between those? im asking because i dont wanna spend 40 euros more for 20mhz of clockspeed. so is there any major difference? 

 

Examples of Graphics cards:

KFA2 1060 6GB OC - 1518Mhz 229€

MSI  1060 6GB OC -1544Mhz 248€

ASUS 1060 6GB OC -1569 287€

If they are all the 6gb ddr5 version than its just the cooling solution and maybe the pcb which in the end doesn't matter all that much as long as it isn't a terrible cooling solution. There has been rumors of a ddr5x version which might be a good deal faster but I doubt any of those are that version.

No there is no major difference once you overclock it yourself.
