Help on custom mini itx build

[Windows_Live213]

Currently the system has:
Asus direct cuII gtx 770
I7-4790k
Asrock z97E-itx/AC
Corsair cx600m
Corsair 250d
16gb ram
An sdd and hdd and blu ray drive
I want help on whether or not I should continue to upgrade. Currently I am a college student so I don't get much money but I do get some and more than willing to put it towards my system but with the upgrades I want it may take a while. The help I want is
1) whether I should upgrade to a gtx 1080
2) should I water custom water cooling this pc
I'm having trouble with this because I don't want water cool my 770 if I upgrade it to a 1080 down the road because the blocks are expensive. Also I want to know whether I should upgrade to a 1080 because that's also expensive about $700 when I got the current 770 I have now for $100 used from a friend. I'm just having trouble deciding because I know the 1080 is a beast compared to a 770 but I want to constantly be upgrading my pc. I also feel if in going to put a 1080 it deserves a Skylar process. Can you guys please offer me insight on my situation.

Your money will be far better spent on a better GPU than on a very expensive custom loop watercooling colution. I buy new GPUs every 3 years or so. So it costs me less than $100 per year to always have good gaming performance, and thats with me not selling my old GPUs (I like my computer graveyard.)

Any reason why you want to upgrade right now? Are you suffering in performance? Or have you just ben bit by the upgrade bug?

upgrade the GPU if you want to. No reason to move from an i7-4790k to skylake unless you really want some new features on the motherboard. It won't even come close to be being a bottleneck to a 1080.
