[SOLVED] Upgrade?

[NatanTajak]

I already asked a question on what CPU I should upgrade to, and a kind guy helped me out!
However, I want to know if I should upgrade anything else, so I can play all the modern titles.
Here are my full specs:
Corsair Graphite 780T
Intel Core i5 2400
Asus P8P67 Motherboard
Zotac GTX 980 AMP! Edition 4GB
16GB Corsair Vengeance DDR3
OCZ 600W 80 PLUS PSU
Kingston HyperX 120GB SSD Boot Drive
Samsung 1TB HDD

I got told by another member to upgrade to an i7 3770K as it is the perfect one for my gpu and motherboard. I want to know if there is any other part I should upgrade, or another cpu that would be compatible with my motherboard.
I get stuttering in Battlefield 1 Ultra and high and even medium, but Rainbow Six Siege runs perfectly on Ultra?
Call Of Duty Warzone is also stuttering and unplayable.
Would love if someone could help and tell me if upgrading to i7 3770K is a good choice, and what other component I should upgrade, or leave as is. Thank You!

i7-3770K is the best CPU your mobo supports.

A GTX980 is decent still.

Larger SSD would allow you to install more games on it.

So just a CPU upgrade and a larger SSD and I should be good?

i7 3770K require bios 3207 or higher for your motherboard to work so make sure you update it first with your current CPU i5 2400. Here is the list of CPU supported by your motherboard.
