So stuck with 5 days without a computer, because my motherboard died (still waiting for a RMA e-mail...) I went ahead and ordered new parts namely motherboard + CPU.
Motherboard of choice was the Arock z97 Killer even came out 1 week ago which is perfect! I really like the board, also boot times are very very, you only get to see the Asrock boot screen for a split second then it boots windows which was noticeably longer with my Asus P8z68 Deluxe.
I went for a budget CPU, because I didn't feel like spending almost 300 euro at this time. The 4670k is still an excellent CPU with abit OC/tweaks it still has great performance.
Nice temps even for clocked at stock.
