Recently got my hands on a nice gpu, I know I'm not experiencing the full potential of it with my current build so I'm trying to figure out the best option for now. I don't have a big budget right now so kind of just want to replace the biggest bottleneck but also want to look into the future. My question is should I just replace my cpu, (if so which one is the best?), or would it be better to just replace everything currently outdated? My current specs: 3070ti, i5 7600k, 16gb ram, z270 gaming m5 mobo, 650w psu. Thank you!
