Dude , invest 100 euro for a msi h110m motherboard and get new pentium g4560. I have it and it runs very good. I paired it allready with rx 580 (sapphire is crap take gigabyte if so) , gtx 950 etc. I suggest you buying both cpu and gpu. Yes you need a new motherboard , it needs a new socket. Keep in mind if you buy h110m motherboard you need to update bios , so i recommend asking the shop to do that for you.
