Currently running a P8Z68V-LX MoBo w/ i7 2600k on a Hyper212+ cooling solution. My intentions are to get the most I can out of this chip (GTX480 card) for gaming. I have a P8Z77V-LX just sitting here doing nothing - is it worth swapping everything out? Will I notice any more overclock headroom? Will it run cooler? As far as I know, and please correct me if I am wrong - the Z77 only adds PCI 3.0 for Ivy Bridge chips. I do not have any PCI 3.0 devices nor do I plan on getting any, anytime soon. Thank you for your time. Love this forum; you all rock.
