For gaming there's about a 1fps difference in favor of the i5-5675c over the 4690 at stock. Broadwell was never about performance gains, it was an efficiency bump on a smaller die. Skylake is the performance boost. Grid was the exception, but seeing as how the broadwell i5 kept up with the 4790k it did so without needing hyperthreading. Meaning your 4690k oc'd more than makes up for the gap.

It makes little sense to upgrade every time a new cpu is released unless you just have money to burn, enjoy swapping components and reinstalling windows with every motherboard change. That's why people are still gaming and getting solid results with the 2500k which is 4.5 yrs old. Most 2500k owners are just now looking to upgrade to skylake for something with enough performance to be worth the cost. I don't expect anything different from the 4690k/4790k, they will likely be keeping up with the latest games and gpu's for the next good 3-4yrs, past skylake/cannonlake.

There are titles such as BF4, Metro LL, Crysis 3 and AC unity that take advantage of the extra cores and cache of the I7.

BF4 23 fps advantage stock vs stock -- MP will be impacted even more
Crysis 3 13 fps advantage
Metrol LL 30.6 advantage

More games are starting to take advantage of the extra resources of the i7.

These gains were with the 780 ti which is significantly faster than the OP's GPU. The reality is that selling the 960 and upgrading the the 970 would probably be a better way to spend the money.

Interesting results when everything is turned down so low (720p) on the eurogamer site. With a gtx 770 @ 1080 there was only 3fps average fps difference between the 4670k and 4770k.

Granted not the same identical chips, but close. With a 780ti classified, the difference between the older 4770k and 4790k was less than 1fps.

Once played at higher resolutions with cards like the 780ti (same as used on eurogamer's tests) the fps difference between the 4690k and 4790k isn't near 30fps, usually far less than 13fps. Some people may still be playing at 720p, but I think chances are if they're gaming with a 4690k/4790k they're probably at 1080 and now many are moving to 1440p.

There is a significant difference @ 1080p & 1440p.
I've done the testing.

I've never done the testing with a midrange gpu such as the 960 or 770.

Most likely the op will use 1080p 60.Hz and the advantage will be less pronounced.

The 4790k allows higher minimum and avg fps and delivers a smoother gaming experience in the titles I Mentioned with high end graphics cards.

There are some titles I left out and in the future more games will benifit

I remember using the metro benchmark and the 3570k & 4670k would get a min fps under 15 fps with a 780 or 780 ti. When I tried the test with a 4790k @ 4.6 the min fps was over 25 fps. Things may have changed as this test was done last fall.

This is just one or many examples
