Help with what monitor i should buy next

Hey guys,Been a fan of Tek Syndicate on youtube for a loooooong time now and i've decided i should join the forums.

So the monitor i'm using at the moment is the Samsung SA700.

It's 1080P LED 120hz 3D and it's a fantastic monitor.

 

Now i'm looking to up my Resolution game with one of the following monitors.

 

So i either want to buy the Samsung U28D590 or the LG 34UM95.

 

My Setup i'm using at the moment is the following.

 

I7 3820 @4.4GHZ

Corsair h100i

EVGA GTX 780 Classified 

Corsair Dominator platinum 16gb at 1600mhz

Asus Rampage gene iv

Corsair AX850 Gold PSU

Samsung 830 SSD 120GB

Samsung 840 SSD 500GB

Seagate Barracuda 3TB

 

I live in the UK and the difference of the monitors is £300 so about $500.

 

The Samsung 4K monitor is £499

The LG monitor is £799

 

Is the price worth doing getting the LG monitor?

 

Both monitors have pro's and cons.

Only thing i can think of is the following

 

Samsung 

Pro's

£499

4K resoltion

1MS response time

 

Cons

TN 

Wobbly panel 

Might require 2 gpu's to play at 60 fps.

 

LG

Pro's

IPS

3440X1440 

21:9


Cons

5MS (Never played on a monitor with less than 2ms)
£300 extra 
Games that don't support 21:9 look awful with black bars.

 

What should i do? 

Thanks all really appreciate all response and i'm glad to finally be apart of the Tek Syndicate forum.

Out of those 2 hands down the LG - IPS all the way. Resolution wise - yeah bugger all things support that ratio but for everything else I would imagine its a dream to use.
