GTX 780 vs R9 290x? i would pick 290x why? i have the same problem once when im building my new PC. i searched and searched a lot of references that sapphire R9 290x tri-x is better than GTX 780. low temp, low noise, and better when playing in high resolution . but if you want a cheaper one buy sapphire R9 290 tri-x it is cheaper and less consumption of power than 290x but still can perform better.
