I've just bought a 4770k and Asus Z87-A motherboard and I must say this is the flakiest (is that even a word) system I have ever put together...
To say I'm not happy with it is an understatement. I've not even began to delve into the overclocking side as this thing isn't even stable at stock. Applications/games just disappear when using them, until the system blue screens...
I'm seriously thinking about DSR'ing this and getting a 3770K and Z77 motherboard as this system has given me lots of issues in the last 2 days that I've had it - it' doesn't boad well for the machine in the long run.
I had to flash the bios to get it to recognise my PCI ASUS Xonar Sound card, which is kind of ironic..
Not happy at all
