EVGA gtx 660 SC to ASUS strix 970 or put the money on other parts?

Hi everyone!
I'm in a bit of a dilemma here.
I bought a Packard bell PC about 6 years ago
But over the past couple years I spent a bit of money on it.

Before____________________ Now...
Intel i3 550_________________Intel i7 860
3x 2GB Ram @ 1333MHz______4x 2GB Ram @1333MHz (Max is 16GB)
Nvidia GTX 420 1GB__________EVGA GTX 660 SC 2GB
1TB W.D. Green_____________ 1TB W.D. Blue 1st + 1TB W.D Green 2nd (Max is 3 Drives)
OEM 250W PSU_____________ OCZ ZS Series 650W 80+ Bronze PSU
OEM wireless adaptor_________ ASUS PCE-AC56 802.11ac

I still use the same old motherboard that it came with, but my CPU seems to get the job done.
I was always after an energy efficient gaming PC for 1080p gaming.
But was wanting to play games at 2k resolution with my 49" 4k TV (HDMI 2.0),
as well as 1080p for normal usage on my 32" TV.

I'm starting to notice that more games are using over 2GB of Vram.
I was maxing out games at 1080p like Tomb Raider and Batman with around 50-60fps but now it seems like I'm always having to drop more and more settings just to get the Vram from maxing out.

The thing is that I'm not in an urge to upgrade my gpu now, especially as the 970 hasn't dropped in price for a long time going now, so it will be inevitable. Worst thing that could happen is price drops just a couple months after just spending a lot.
So that begs the other option, to upgrade my actual pc, or maybe even sell it all and start off fresh with a completely new build?

Hello ! Since your processor supports DDR3 ram, this would be the best idea at the moment . If you already have 4GB DDR3 then add another 4GB stick to minimize stutter and low fps. Plus when you build a new computer the ram could contribute to it .

I would first find out if that prebuilt will support newer 900 cards as most can find out no.... I'd do some good home work on that before I spent and see proven cards working in your model not the old ''ya, it will work'' spiel
