Hi, thanks for the guide, really good to see so much information out here! I recently began building my own rig (click for details) and decided not to go for the 4770k but for the 4790k, since the price is almost the same, but recently got told, that I would need to update my BIOS version to F8 in order to have it work. So since I don't have another CPU for the socket lying around do you think it's possible to flash the BIOS with the CPU or won't it work at all, if it works, which method would you recommend? (I only have an OSX and a Linux machine, no Windows) Also how will the BIOS flash affect the ability to run OSX? Thanks in advance guys.
