well, look up the games you play with the 290x vs the 780 ti, they trade blows. however, within the next couple years as games start being able to use hyperthreading, then the i7 4770k will be better. if the games you play get better performance with the 780 ti, then pair that with the xeon E3-1230 v3, it is pretty much an i7 4770 without the graphics, but cheaper.
