That are the parts i am buying.

I am a complete "noob" with computers and i am not sure if my PSU will be enough.

 

This is in my current pc:

 

PSU: Cooler Master GX Lite 600W PSU

GPU: Sapphire Radeon HD6870 1GB GDDR5 PCIE-E

Case: Cooler Master CM 690 II Advanced Black

will these be good?

the use of my computer will be gaming. mostly Dayz. I have heard the game is very cpu demanding.

I don't know specifically about DayZ, but I think your choices look fine.

You don't have any RAM listed. Do you already own DDR3 that you are planning to use? Do you need to consider that as well?

 

The video card (GPU) you listed is 2 generations old.  The 7870 or R9 270/R9 270x is going to be better bang for your buck.

He is reusing parts from his old build. That GPU is the one in his current rig. I agree that a new GPU would be a good upgrade, so maybe he can keep it in mind for the future.

Ah, I see that now. :facepalm: Makes sense.
