So I have a question about water cooling and sorry in advance if this is the wrong thread. Didn't see a water cooling thread.

I am designing my first water cooling system. It is external and housed in a Cooler master HAF F case. I want two 360 mm radiators for 3 Zotac AMP gtx 680 water blocks. This is for graphics only and probably overkill. However, I want to know if I need two pumps or one. The loop would look something like this:
Pump> rad>
Res > [ ]> Y fitting > gpu
Pump>rad>

And back to res. Is this necessary? Also what can I use to power this?

Yes it's completely %100 unnecessary, you're right now looking at cooling about 1200w when you really only need to cool about 600w or so. This is never going to get below ambient so it's pretty pointless. As far as if you need 2 pumps it depends on what the pressure drop of the radiators is and the power of the pumps. There is actually a stickied thread here that tells you how to select a pump based on pressure drop. Also not sure of what you have in mind for a 'Y fitting' but it doesn't matter what order the water flows in. It will all be the same temperature regardless of where it is in the loop. Think of it as your radiators are cooling the entire body of water at one time not just what is flowing through it. Reason for that is because all the water is touching and the heat transfer is happening instantaneously regardless of what area it is in.

Alright. Seeing as it is completely unnecessary and id still like to try doing it for the experience, id like to know how would you set this up? In terms of the "Y" fitting its basically a split that will go on the output of the pump. but since it doesnt really matter in that sense, should I just make it all one loop? Reservoir>Pump>360Rad>360Rad>GPU block>GPU Block> GPU block> and back to reservoir? Would that be sufficient enough?

Yep, the only thing that matters is having the reservoir above and directly before the pump.
