Hi, i would like to switch my i5-8400 with something more powerful, i was thinking about buying used i7-8700 and pair it with my current b360, lets say i7-8700 used in my country costs "800", on the other hand i can buy whole new platform with z490, i5-10600k and new cooler for "2100"(everything new of course) is it even reasonable? or should i just stick with 1151 and buy used i7-8700? would difference even be noticeable? in future i'd like to switch 1660ti with 3060ti/3070 but we're talking about years from now, like 2-3 years.
