I am planning on getting an i5-3570k CPU and an ASRock Z77 Extreme3 ATX LGA1155 Motherboard, but I've been told that the main reason people buy that motherboard is for overclocking. I've never built a computer before, and I don't know the risk vs. reward of overclocking. Should I do it for my first time, or is it too risky? If I shouldn't do it, should I get a different motherboard? (maybe one that's a better price for same performance idk) And lastly, if I shouldn't do it, should I get the i5-3570 instead of the i5-3570k? Thanks in advance!
