I need feedback on the PC components I've chosen for a new build.

[TheHuman]

Hello. This is my first time building a PC and I need experienced people to comment on the components I've chosen. I will use it for gaming and of course the usual things like browsing the web. Does anything stand out as being a stupid choice? I'm also wondering which cables I need to purchase besides the ones included with the power supply. I'll use a regular monitor, possibly the LG IPS277L.
I appreciate all comments!

Whats your budget limit?

You don't need 16GB RAM for gaming.

Why not get a GTX 770?

Water cooling would probably be better for cpu cooling.

I'm not in America though, so I can't purchase all of the parts that Americans can, especially not for the same price. I guess I could still use the site to get an overview of the things I'm planning on buying. I'm thinking of spending perhaps the equivalent of 1600 dollars.
I know 16 GB of ram isn't needed for gaming, but I often have many tabs open in my web browser with a lot of content, including video. The graphics card you suggested is kinda expensive. I've read the reviews of the one I included in the list and people seem to enjoy it. I know it's not the greatest, but it does seem to be powerful enough for good gaming.

How much of a difference would water cooling give me?

Water is much more thermally conductive than air so it is much more efficient at exhausting heat, but low quality cheap water coolers are worse than mediocre fan coolers. If you decide to go with water cooling I recommend the Corsair H100i.

Regarding the cables, are all vital cables included in the PSU? I assume I'll have to buy USB cables to connect the USB ports on the motherboard to the case, but is that it?

All vital cables are always included...obviously. You most probably won't have to buy usb cables, they usually come with the case.
