New GPU more?

[Gspopp]

So, I'm having this internal battle with myself and I can't seem to come to an actual answer.

 

The question is simply do I upgrade just my GPU or everything?

 

My current Rig;
Case: Corsair Obsidian 750D Full Tower Case
CPU: Intel 4820K 3.70GHz (Ivybridge-E) Socket LGA2011 running at 4.4ghz
Cooler: Corsair Hydro H105 Extreme Performance Liquid Cooler
Mobo: Asus P9X79 Intel X79 (Socket 2011)
RAM: Corsair Vengeance Pro 16GB DDR3 2133MHz Dual Channel Memory Kit
GPU: Asus GeForce GTX 780Ti DirectCU II 3072MB GDDR5
PSU: SuperFlower Leadex GOLD 1000W Fully Modular "80 Plus Gold" (Overkill I know but this was because the 850w Corsair was no longer in stock and OCUK substituted this in instead)
SSD: Samsung 250GB SSD 840 EVO
HDD: Seagate Barracuda 7200RPM 1TB SATA 6Gb/s 64MB Cache
 

Now I know my system is old but it's served me well. I am running a 1440p uw monitor and it's struggling a little now.

So will buying let's say a rtx2080 solve my issues or is my cpu going to bottleneck me? Do I upgrade everything now or wait for ryzen 3? Or will my current system still manage? 

 

Any thoughts?

I've seen people using a 4770k or 4790k on overclock with it, so it shouldn't be much bottlenecking.

It will manage just fine!!!

Ok well this does appear to be the general response I'm getting which is good. 

So if I were to get a 2080 do we have any preferences on which? Price to performance wise which would be best?
