Was able to fit these parts into the €600 budget.
Went with the regular i5-3570 because I'm not sure if you can overclock on the B75 chipset and it fit into the budget (i5-3570k went over by €19).
Caviar blue HDD instead of Caviar black, Micro-ATX Motherboard, only 80-Plus PSU, well, because, €600 budget.
Hope that is any help.
Here's a Radeon HD 7850 benchmark.
