I'm currently running a 2600k, 16GB DDR3 and a GTX1070 I want to play on 2560x1440 at a confident frame rate to make use of a high Hz monitor. My friends are encouraging me to upgrade my CPU, Motherboard, RAM to the latest and greatest. Is that really necessary at this point? My own feelings are that the 2600K still has a bit of punch in it and that investing a hefty amount on a new GPU alone should do the trick. Am I stubborn or is there some truth in what they say? Last thing I want is a huge bottleneck. Many thanks!
