custom water loop or closed

which is better? and is there a way that i can extend a AIO cooling system to my gpu some how? or do i need a seperate cooling kit for my gpu

Since you have to ask, you probably have no experience with custom loops so you'd be better of with AiO. There are some new ones that have a GPU cooling in the loop or you can have separate ones. Some GPUs even come with their own liquid cooling which could end up being cheaper than adding one after.
All of that under condition that you do need liquid cooling at all.
I can see only two reasons to make custom loops, either for looks and bragging rights or insane OC.

The thing is i currently have a reference gtx 1080 which gets really hot underload, i even overclocked which made the temp go up to even 88, 89 celcius. Quite honestly my cpu runs pretty cool on air, just my gpu that is causing the heat, what would be the best solution, can u recomend some gpu liquid cooler for around 100 dollars max

There's this new Kraken https://www.nzxt.com/products/kraken-g10-white that's supposed to be good bargain.

What good liquid cooler would go with that? And is the evga hybrid 1080 liquid cooling kit worth it? Comes with everything

You mean expandable AIO? there're Swiftech H series, EKWB XLC Predator and Fractal Design Kelvin, those are mainly CPU water cooler with option for CPU + GPU watercooling depend on radiator size, usually 360 radiator is suffice for 350 watt TDP (i.e. 125 W CPU + 225 W GPU or two 175 W GPU).
The problem with two GPU AIO is

• 
  ■ when there're no more room left to mount two radiators, such as NZXT Manta (two 240 mm radiator).
  ■ high end GPU overclocked TDP is over 200 W, makes push pull 140 radiator meet the cooling limit.
  ■ AIO pump was not design to coupe with other restriction point, you may hard mod AIO but the AIO pump's low flow rate and other water block pressure drop will slowly killing the cooled components.

SO DON'T , NEVER HARD MOD your AIO.
