Hello everybody, I was just wondering whether its worth to upgrade my cpu from an i5-3570 to an i7-6700k. If I did this I would have to buy a new motherboard and new RAM as well, but I was also considering to upgrade my GTX 970 to a GTX 1070 in order to get better frames on my 1440p display. I'm not sure which to purchase for Christmas because I can't buy it all in one place.
