Upgrading pc

[Tyler004]

Ok don’t laugh I bought a pretty cheap pc and specs are:

I5-2400

GTX-1660

RAM 8GB 

motherboard is 

Asrock h61m-dgs 

can someone help me please I’m noob and wanting to get a better cpu so I can run some newer games I’ve looked online and apparently the I7-3770k is the top one I can get for this motherboard or is there something better?

yes, 3770k is the top one you can get.

either the 2600k or the 3770k, there's not much difference between the two
