Okay so i have a r5 1600 currently and i'm looking to buy the 1180 or 1080ti, but for further advancement for CPU is it worth staying at the r5 1600 and upgrading other parts like my 8gb of ram or to go to one of the following (i7 7700k or r7 2700k) i feel like and research the 7700k is better for gaming which all i will mainly do. But that would require buying a whole new MoBo and i do not think it is worth it? Opinions.
