In my country R7 1700 and R5 2600 are going for the same price. I know that the R5 has higher boost clock but the R7 comes with a better stock cooler.
I plan on overclocking though.
My priorities are gaming and video editing btw.
if you getting r7 1700 for same price. just go for it..
and u will need an aftermarket cooler for overclocking it, if you plan on increasing clock speeds significantly .. u can use stock cooler for 100-250mhz increase at best i think.. after that things run bit hot under full load..
