Since you're only doing 1440p 60hz a 1080 should be plenty to run all your games at high settings. The Board itself is a little on the expensive side but it's got a metric butt-ton of features and it looks awesome so price might be justified a little bit. I'm personally not a fan of that card especially since it has orange stickers or lights (I cant tell which it is) as I feel like it doesnt truly match the color scheme other than being mostly black, which so many cards fill that requirement.

If it's a founders edition, it will look like this:

regardless of the manufacturer[Asus, MSI, Gigabyte, Zotac, etc] (Super bright green LED logo on the front)

If you're looking at EVGA's SC 1080ti, it will look like this

Which fits your color scheme much better and has significantly less LED lights on the card (the logo is white so thats good) this card is pretty decent, not as good as the FTW version in terms of cooling and noise but still a good step up from the Founders Edition
 
That the 1080TI though, the EVGA 1080 FTW looks like this

Cooling wise it functions the same as the 1080ti but slightly better thermals because the 1080 isnt as hot as the 1080ti. This is the card you've probably heard at one point had issues with heat, but those problems were fixed last year (It was a VRM issue, the thermal pads were bad but EVGA has fixed production since then)

even a 500W psu would be fine, the card eats 150W without overclocking max

The gtx 1080 would be a good choice still if you are gaming at 1440p 60hz because you will be able to game at that resolution and refresh rate for quite some time with no compromises. The gtx 1070 is good for 1440p 60hz now but on a few years that may very well change.

Hi, the RAM I choose is Galax HOF 16GB 92x8GB) DDR4-3200.
About the cable kit, it is female to male (maybe something wrong on pc part picker because i import infor from amazon).
Anyway, thank you
