I guess both are 3000 USD+ cards....
Hi Upadhyay,
Yup, you are right both GPU is really expensive. That’s why in my previous post, I recommended you GTX 980 GPU, based on my experience with it. The GTX 980 GPU is 35% faster than GTX 780 Ti, 73% faster than R9 290X because its architecture is supported by Maxwell architecture, due to that the Video support or graphics are quite good.
In short, you're getting a powerful addition to your PC that not only lets you turn your 1080p monitor or HDTV into a QHD beast, but also have powerful pixel if you're a gamer, graphic professional, 3D artist or video editor.
