I wanted to build basically a computer which would last me on all the next gen games until new consoles come out my question is will this do it and are there any changes which can be made to make it better while keeping a similar price? http://uk.pcpartpicker.com/p/FXmRgs
The GTX 750 TI is pretty similar to the PS4 GPU, and stronger than the X1 GPU. That means you'll run next gen games fine... At 900p, 30 fps, just like the PS4.
If you try to push for 1080p 60 fps in next gen games, you'll have to settle for medium settings.
You should switch that CPU. The "K" on the end just means it can be overclocked for about $30 extra. Since your motherboard isn't capable of handling an overclock, there's no reason to get the "K" CPU, so...
