Having a 1080 you sure saw difference. I had a R9 270X and was hoping to get an RX570. I wouldn't notice a single frame difference between 2500k and 6700k. Battlefield 1 also uses well past 4 cores. Give him 8 cores and it will use them all. i7 choke on that game. No, it is not. Specially if you wanna stream/record. Plenty of games can use more than 4 cores. You bought intel so you're ****ed: want a new CPU? buy a new motherboard. As for DDR4, the next gen is still some time away.
