True

Easily the 752's.
 
Arctis are bad all around, Razers audio products still haven't gotten better.

Οχι δεν θα έχεις κανένα πρόβλημα. Επίσης το Freesync λειτουργεί περισσότερο όταν πιάνεις 40-45 Fps και σε κάνει να νιώθεις ότι παίζεις με 60 Fps. Η RX 560 είναι καπος αδυναμη καρτα και ούτε καν τα 40 δεν θα πιάνεις με καλά γραφικά για αυτο είναι καπος αχρηστη

Ε τότε πάρε την 1050 Ti, η μόνη επιλογή φίλε...

Forget about Freesync! Just get the GTX 1050 Ti. It's a much powerful card

Freesync imo is pointless unless you plan to get less than the refresh rate, which in this case is 75hz which is easy to hit in most games at high at 1080p, even if its an ultrawide. The 1060 6gb would be the better option.

For editing and productivity the dell wins.
Gaming and such- LG. You still have IPS with LG and you get 75Hz which will feel smoother than 60Hz at gaming.

Priorities in graphics should be IMO :


Quality ( high, ultra ) ---> Resolution --- > anti-aliasing

So I would say : Ultra 1080p will look better than medium 2K

In my opinion 1080p 60fps. You got that 60fps and ultra settings look. Of course it depends what you care more about. Is it smoothness and quality or simply the fact that you game in 2K. It's all up to you  

I think it depends on what game you're playing.  But, generally speaking, i think the ultra settings at 1080p would look  better just for features that you can turn on, like foliage density, shadows, render distance, or hairworks like in Witcher 3

i prefer 1080p and ultra settings, just my opinion though

24" and below 1080p.

I don't know if either resolution will make comic sans look better.
 
I'd personally go with 1080p 60 FPS. Frame rate has a bigger impact on gameplay than just turning up details. You're also not going to find a true 2K monitor everywhere, but more commonly 1440p, which is slightly higher than 2K.

What do you play?
 
FPS, e.g. CSGO, then get a High refresh rate
 
Otherwise its just a case of getting the best resolution. Potentially a G-Sync monitor may be worth it if you want to have a smoother playing experience.

That would fit just like any other 120mm fan. The pwm version would be more appropriate though: https://www.skroutz.gr/s/3375761/Noctua-NF-S12A-PWM.html

I use Bequiet Dark Rock pro , the only thing i found doing less noise than noctua fans.
Locked at 800rpmit can handle my 4690K oc 4,5Ghz.
 
maybe get a cheaper version with only 1 fan if it's only about noise.

The mounting brackets can be removed to accommodate any standard fan with 120mm mounting holes. 
Noctuas are great but they are a bit more expensive. If you don't mind the extra price, feel free to get them.

No, they're not better than Noctuas but they are cheaper. 
I don't see why you'd buy two of the fans.. A second fan doesn't improve performance much and would block your ram slots again. 
Why would you use your Corsair fans if the issue was that they were loud in the first place?

The best way is gtx 980 ti
and cheap solution is you can find 2 used gtx 780 ti and You have a 4k  

X-Silent's are good: http://www.skroutz.gr/s/2273693/Thermalright-X-Silent-120.html
If you want to go with 140mm, Viper R is a good alternative: http://www.skroutz.gr/s/6892973/Akasa-Viper-R-Fan-140mm.html

Which shops are you using? Can you link us?

Any fan with standard 120mm mounting holes should work fine. Where are you shopping/located?

water cooling adds noise to your computer due to the fans used to cool the radiator and from the pump which is used to move the liquid through the cooler. There are some units that are quiet but if you really want to cut the noise you should consider going with an air cooled solution. That said you seem very set on liquid cooling for aesthetic reasons. If you go with an AIO cooler plan to invest some extra money and replace the fans with noctua fans. They are expensive but they are also super super quiet and will reduce the nose you are hearing. You might also consider replacing any stock cooling fans you have in your case. 
 
When choosing a water cooler read some reviews and watch some videos of models that you are interested in to see what will work best for you. I understand that the NZXT models tend to have good performance and lower noise but I don't personally use water cooling so I can't recommend a particular model. Also, please note that you posted this to the AIR COOLING sub-forum. You might get better advice from the liquid cooling section. 
 
Good luck!

Why's that? From what it seems, it's not like your current cooler isn't performing well enough. If it's too loud, you can just replace the stock fans.
