I am looking for the difference between these mobo's, I know p8z77-v has integrated WIFI support, but is the p8z77-v it worth the extra 60 bucks for the WIFI and other features I might not have stated?
The choice entirely depends on your needs, GPU and CPU selection and OC plans.
The P8Z77-V LK is a good basic SLI Z77 whereas the P8Z77-V also offers SLI and is much better suited for OC'ing with the (K) SB/IB CPU. Most folks won't notice the LAN difference Realtek vs Intel LAN (Intel is better), nor do they need more than 6 SATA ports from a third-party chipset e.g. ASMedia, nor have the need much less the desire for WiFi on a desktop PC - use the LAN (CAT-5e/6 or PowerLine), but those that OC need the additional Phase/VRM of the P8Z77-V or P8Z77-V Pro.
So if you're looking at a SB/IB (K) CPU and in that budget range either the ASUS P8Z77-V or ASRock Z77 Extreme4 are decent starting points. Otherwise Phase/VRM won't matter and the ASUS P8Z77-V LK is a good choice if looking potentially at an SLI (nVidia) GPU solution. The additional Phase/VRM aides in reducing the vCore and stabilizing the OC, which adds long-term CPU longevity, higher potential OC and lower temps.
