Do I need a CPU Upgrade for Gaming?

Solution
I5-4670 which the OP has is still good.
Note that this is not as strong as an overclockable i5-4670K
Why not try the new games and see how you do?
Some games will be graphics limited, and some will be cpu limited.

If the particular games you play do not play well, then decide on your options.
