Graphics card for 1080p or 1440p gaming

[Wubcat]

Hi, I live in Australia and I have had some trouble deciding what graphics card I should buy. I will only be playing games at 1080 or 1440 if I decide to upgrade my monitor.
Where I live, the 290 is cheaper than the 780. The 770 is about 70 $ more expensive than the 280x, and the 270x is alot cheaper than the 760. I will be playing bf4, rust, day z, skyrim and other some other pc exclusives. I am switching from consoles so any help is appreciated.
Thanks

I'd go for the 280x.
an extra $70 is not worth it for the 770, their performance is pretty similar.

Thanks for the quick reply. Is it worth getting a 290 for 1440p if I go down that road?
