if you're just going to be gaming on it (and dont have need for extra cores/hyperthreading) - stick with the i5. Get the 4690K if it isn't too much more expensive simply for the option to overclock later, if you feel like it. Its easier than ever (you could OC it to 4Ghz on a 40$ (US$) air cooler).
Depending on the costs (i know i just did a build for a guy in AUS$ and holy crap does the VAT screw you guys) - consider a GTX 970 even if you play largely at 1080p - the larger VRAM pool will lend it longevity vs the 960.
8GB of RAM is likely fine if you dont do much more than gaming and light background tasks.
I consider (at least in US$) the sweet spot to be around 900-1100 for a "bottom of the high end" rig. Here, at least, you can get a GTX 970, i5 4690K, and 8GB of RAM and that will generally crush gaming at 1080p and last several years.
