I know that feel bro.
The gpu is a beast and you cant wait enjoying it. I underestand.
I had money for any build but i did 45 days to build it,with patience,in the end i builded it for 1700euro instead 2100 it was when i first planned on my build.
With 400 euro i bought roccat kone xtd gaming mouse(awesome),roccat kone mouse pad with crystal surface and shits(awesome),corsair vengease k90 gaming mechanical keyboard(freaking awesome), 2 xbox gamepads for pro/fifa,2 white cold cattode labs to light up my tower,and a usb fan for my hand to not sweat while gaming. All this cuz i was pateint.
Anyway go for it...
