I was also curious about this. My computer uses are gaming (mostly MMO's GW2 and BF3), music production (Ableton Live) graphic and video rendering (CS6) and coding (JCreator and Adobe Dreamweaver)
The CPU's I am looking at are the 4670K, 4770K, and the FX 8350
For graphics I am going with the GTX 780
Mobo Gigabyte Z87
I plan on building it today any help would be greatly appreciated.
