computer

Having a big issue here wether I should get i5-8600k, i7-8700, or i7-8700k. I don’t plan on overclocking my cpu so I don’t know if I the K for i7 is worth it but if you could help me on this is basically the last thing I’m deciding on before I build my pc... Btw i5K-$237 i7-$298 i7K-$348

So I’m building my first computer it’s for my senior project and will be using to game with y’all again. If you all will tell me what to change or keep it would be nice. I have a budget of 2500 can go over a bit but not to much. So just give me your straight opinion whether it’s straight garbage...
