(Before I start I just want to mention that im not crazy good with computers so please bare with me) I had built my first and only pc back in summer of 2017, everything went as planned, but as it gets older, it gets harder and harder to run these new games at the settings I'd like. Right now Ive got a Nvidia gtx 1070 and a i5-6600k. Is it dumb to only upgrade one of them? Or should I just upgrade them both at the same time, or does it not even matter? Also, are there any things I need to keep an eye out for in terms of compatibility with any of my other parts? I forgot the little things that I did learn 3 years ago, having trouble remembering lol. Finally, any reccomendations on what to upgrade to? I'd prefer to stick with Nvidia and Intel but, if theres a good reason to switch please tell me. If you need anymore info please feel free to ask. Thanks!
