yes it is significant and it's up to you.
personally if the cash is spare, i'd go for it. no such thing as too much horse power and how well will that 970 drive a 1440 screen?
though this is coming from someone using a 980ti 1080/60. games feel best at 70-75 fps cap using fast sync (perfect 180 turns/sweeping sniper scopes, ect.) if i'm using only 60%-80% of the gpu i turn on DSR (1440)@12%. i'm still patiently waiting for a good 1440 screen in my budget but until them, i'm good.
again, if you have the spare cash.
Remember the golden rule of statistics: A personal sample size of one is a sufficient basis upon which to draw universal conclusions.
