The reason I chose 4th gen is because my CPU, MB and RAM alone comes to $140 cheaper than yours. That's a bit more than $25. Yes if the budget was bigger I would be more inclined to use skylake, but its not this time. Besides, you are $120 over-budget for him, which includes your missing storage. The 4690k may not be the latest CPU but a 4th gen build with a GTX 980 will certainly crush games well into the future.
The price difference in motherboard/ram between your build in mine isn't purely a result of 4th gen vs. 6th. I could pick a cheaper Z170 motherboard and cheaper memory to bring the price down by $60 or so, but opted not to. $1300 is plenty to allow for a gen 6 build, it's just a question of where you want to make compromises. The second build I posted has an extra $85 invested in (I would say very worthwhile) storage upgrades compared to yours, skips the unnecessary optical drive, and although I applaud your taste in cases, going with the S variant instead of the R5 offers an extra $38 for performance enhancement.
I'd agree that a 980 would be nice (I have one myself, but I'm driving a 3440x1440 display with it), a 970 is more than adequate for 1080p, and the 980 only has about 20% better performance for a 40% increase in price, making it another great place to free up some bucks.
If it were me purchasing for 1080p, I'd just go with the 970 and enjoy the extra disk space, not having to worry about setting 25% over-provisioning on my SSD cutting into my space. With games often taking up 30GB each and seemingly growing by the day, it's a hassle that's good to be ahead of. I also think the right time to invest in a more expensive card would be spring next year when the Pascal parts come out, which I am fully expecting to embarrass any Maxwell card on the market today.
