I am purchasing a new intel core i5 2500K cpu. Can someone tell me which chipset mobo I should be looking for? I read that some supported mobos do not let you overclock your cpu. Whole others won't let you use the onboard graphics. I was told certain models let you do both, overclock the i5 and run its onboard graphics. Can anyone help me with this? I've been out of the PC building game a while so a lot of thsi is new to me.
