thanks maktovic for ur replies of my queries last thing pls suggest me. Could i returned this card to seller and take r9 270x vapor x instead of GTX 760 due to heating issues or keep this card and use and see the performance ..
GTX 760 outperforms R9 270x and there is noticeable difference between the two.
With reference GTX 760 expect the heat and noise to be high, heating issues can be controlled by proper airflow but you've to bear with noise, if you think you can live with that then YES , definitely stick with GTX 760. With case fans installed and Stock CPU cooler, they will be the loudest in your case and graphics card blower noise won't be a issue.
There's more than just performance, with GTX 760 you'll get Nvidia exclusives: PhysX, Adaptive VSync, HBAO+, FXAA, TXAA, Geforce Experience, Shadow play, etc. First you decide if you need them or not.
If no then Sapphire R9 270x Vapor-x is the way to go.
