CPU GPU bottleneck multiplayer

I then went on to check some other games same issue after...

So i've been on the edge about upgrading my CPU, question is, is it worth it? should i even upgrade or just build a whole new setup? --------------------------------------------------- Windows 10 pro 64-bit Intel(R) Core(TM) i7-3770 CPU @ 3.40GHz GeForce GTX 1060 6GB SC MSI Gaming motherboard...

Yo guys, I've had my pc for a while now and its starting to run slow FPS wise in games or say a song changes on youtube it will lag me out pre bad Just wondering if you can tell me if its the processor or the graphics card, I bought the graphics card after the pc. Processor is: AMD A4 - 5300...
