the r9-280 and the gtx 760 both can be had for less then 250... and both are superior to that r9-270x listed above.
depends on your preference both cards are pretty equal, though i suggest avoiding 2gb gpus going forward, especially with titanfall and watchdogs starting the trend toward needing more vram.
here are two good choices for you. take the card you like better.
get the r9-280 if you like to overclock (these cards are fantastic overclockers), don't want watchdogs and like a little more $$ in your pocket at the end of the day.
get the 760 if you want watchdogs, don't want to overclock (its a little faster at stock) or want things like shadowplay or maybe in the future plan to get a 2nd card for more horsepower.
I wouldn't have linked it if i didn't think it was a good buy. solid value, good card. the 4gb of vram really takes it over the top imho.
woops, didnt realize you had linked it already. my big concern is reliability. friend is having problems with his 770 and its drivers. not sure if the 760 line has similar issues or not...same concern about othe cards like the 270x 280 and maybe a 280x(if one in the price ranged can be found)
both amd and nvidia cards can have issues. both of those cards should be good. if your friends issue with the 770 has soured you on nvidia then get the r9-280, it's also excellent.
