Can I run G-Sync 1440p on a 1080p Monitor with DSR Smoothly

[RTW970]

Hi all, I just recently built my first gaming PC with these specs:
CPU: Intel i7-4790K
PSU: 750W Corsair
Memory: Corsair Vengence 16GB
Motherboard: MSI z97 Gaming5
GPU: MSI GeForce GTX 970
So soon enough I will have saved enough to get a second 970 in SLI and I'll be looking to do some 1440p gaming but I also want to see if it's possible to get G-Sync with my budget. Unfortunately I don't have enough for an Asus ROG 1440p so I was wondering could I buy a 1080p G-Sync monitor and use DSR to make the resolution to 1440p? I have heard a lot of criticism of DSR but all I want to know is that will two 970s have enough horsepower to increase from 1080p to 1440p with DSR without having a drop of let's say bellow 45-60 FPS?
If not, then I will just get a normal 1440p monitor and will have to stick with V-Sync and get a G-Sync 1440p monitor in a couple of years when they'll hopefully be cheaper.
Thanks

The Dell S2716DG is the cheapest 1440p Gsync monitor on the market, maybe you can afford that?

I don't think I can afford any 1440p G-Sync monitor at the moment. That's why I was wondering about upgrading a 1080p G-Sync Monitor to 1440p with DSR as it seems like the only affordable option for me now to get G-Sync and 1440p. But if I must I will just go with a normal, non-G-Sync Monitor and get a G-Sync Monitor when prices go down.
Thanks for the help anyway.

DSR won't really improve image quality much.

Yeah, I guess so but its still a couple of months before I'll be able to get a monitor anyway so I guess anything could happen in that time

Well might as well get a placeholder monitor until then in that case. No point paying for Gsync if you're gonna replace it in a few months.

I already have a placeholder monitor atm I meant that I would get the g-sync one in a few months if I decided to get one.

Well save up for a 1440p 144Hz one then.

Yeah I thinks that's the best solution. Thanks for the help mate.
