Feedback on Apollo config

Budget:
$3000


Expectations:
1440p / 4k gaming primarily FPS

Hi all,

looking to pul the trigger on an Apollo now that the 1080ti just came out. Have provided my config below. Will be used 100% for gaming primarily FPS - Currently have a 1440p monitor but will look to upgrade to 4k.

My main questions re: config/ help in validation:

-Chose Asus Rog strix Z270H motherboard as I may look to do SLI down the road (Assuming this is ok?)

-Chose 850W Power Supply as I've read this is recommended if you go SLI (recommendations welcome)

-Put in a Separate wifi card as my computer will not be near my router.

-is 16GB Ram sufficient?



Any / all advice on other options I should be looking at or whether I should tweak my current options are welcome!

thanks in advance!

Just to add... the answer is Yes to your questions.

An 850 watt psu for sli 1080ti should be fine. I personally would go 1000 watt but that's me.
