Approachable means you can walk up to it just to confirm "wtf I thought that was a trash can."

Anything Alienware

I had a PC that came pre-installed with Norton once, that was pretty bad. 

Luxury!, we can only dream of 100 square feet. you try living in houses no bigger than most peoples cars over there.
 

Dude, shit in the usa is cheap! you don't know your born. come to the uk and pay $11.50 a gallon and $305 for your 4690k

Stick with the 840, no need to dump it just because there's a new kid on the block, unless you have money to burn.

This would be better alot better @CraftyMiner88

Z97 boards are designed for Devil's Canyon cpus (4690K and 4790K, etc.), so they should support it out of the box.  If you want to use a Z87 board with a devil's canyon cpu, you will have to update the bios (and some boards may not support it).  
 
Did you change anything else in the bios besides core voltage and multiplier?  When you go into the bios, under the "Boot" tab, can you see your hard drives listed (you may have to scroll down)?

Z97 came out for Haswell refresh and Devil's Canyon came out later and according to ASUS you need BIOS 1008 to support Devil's Canyon CPUs.
So you might need a BIOS update or not.

Yes Z97 boards are compatible with the 4790k, in fact I am using a 4790k on a z97 board right now!
