I'm planning on upgrading my pc soon and i don't know if i should just upgrade my cpu to an i5 4690k or get a new motherboard a new set ram and then get a kaby lake-s processor. the 4690k is around 230 and a kaby lake-s processor would be around that or a little more but i would have to spend money on a new motherboard and set of ram. so i guess what I'm trying to say is would i get better performance from the 4690k or the newer i5 kaby lake-s processor. i will also be getting a gtx 1070. oh and is a 600w psu enough power for all this.
