Question Thinking of upgrading my 2013 Alienware 17 laptop , how far can i go ?

[Starwraith]

Currently I have an i7 4700mq CPU , a GTX765m GPU, 24gb of RAM and I've upgraded the hard drive to a 1tb SSD.
Is it still worth upgrading , if so how far should I go.
The main use of the laptop nowadays is for online gaming.
Many Thanks in Advance

Replacing the graphics card should work, but personally I wouldn´t do it because the GPU is very expensive ~300$, even second hand. Additionally a better PSU could be required as well.

The CPU can be replaced as well (this one about 260$):
