Building a PC

[Legend Jam]

Hey Everyone.
I have decided to build a top tier gaming PC, so I can play away.
I was thinking on 2 GTX 980 Ti, and i7 490k, A Coolermaster Full Tower Haf X,
16GB Ram(Corsair Vengeance)
Samsung 850 Evo
LEPA G Series 1600 Watts
Asus RoG Swift PG278Q

I am still a newbie in building computers, and I am absolutely positive that something does not match here. Can anyone please help me if what I have above is right?
And plz, leave a motherboard that matches with these, if you would.
Thanks! 😀

2 GTX 980 Ti's are just an overkill for a single 1440p monitor. You will be completely fine with just 8GB of ram, unless you are doing video editing.
Everything else is good. The ASRock Z97 Extreme6/ac is a good motherboard that i think will handle everything. Also have you chosen a cpu cooler?

Personally i wouldn't blow that much money, because parts get outdated very fast.
