I am building a new computer and have decided on an i7-2600k processor. My primary applications will be autocad, audio / video remastering, math calculations, and some gaming. I've been leaning toward one of the following 2 processors: 1) Asus P8Z77-V LGA 1155 Intel Z77 4xDDR3 , or, 2) ASRock Z75 Pro3 LGA 1155 Intel Z75 HDMI SATA 6Gb/s USB 3.0. Can anyone out there offer me a little insight, advice, or suggestions? Thanks.
