Welcome to the forums! I hope you enjoy building computers as much as we do.
Several things (I apologize, it's late so I have to make this quick):
- Instead of the 3770, check out the 4670 or even the 4570 (NOTE: these are different sockets, so you'll have to change the motherboard to a socket 1150)
- 32 GB is overkill (WAY overkill), especially for a 1000 euro build. 8GB typically is enough for most people's needs
- Instead of the 680, check out the 770 gtx -newer generation; same performance, cheaper price
- 1000W PSU is overkill too. A good brand (Corsair, OCZ, Seasonic ) 650W PSU should be fine.
Hope this helps.
