The "Dash V" (i.e., Video) Pro is a very nice board with a decent feature set, positioned in the upper middle tier of Asus' mainstream motherboards. I have looked at this board a lot, so I can give you a pretty thorough run-down of what aspects I like about it.
First, Asus has a very good reputation and is generally considered to be one of the top 3 mobo manufacturers in the industry. All of the Dash V mobos offer excellent controls. The UEFI and software package (AIsuite) are both top notch. The Fan Xpert 2 software is phenomenal. There are plenty of videos available on both Newegg and YouTube to help educate you on the specifics, so I won't go into those in any further detail.
Other features which I like are the full ATX form factor, which provides room for running parallel video cards (either SLI or CrossfireX), either straight out of the box or sometime in the future. That is a nice feature for gaming, since it will generally yield higher average frame rates for smoother gameplay by minimizing input lag and choppiness of the video output to your monitor.
The Z77 chipset works with both Sandy Bridge and Ivy Bridge CPUs, so you can start off with a cheaper Sandy Bridge (Gen 2) processor and still be able to upgrade to more expensive Ivy Bridge (Gen 3) processors down the road.
Other nice touches are the Intel NIC (higher quality than other NICs) + on-board WiFi (doesn't require a separate card to be added later), PS/2 keyboard/mouse port (useful for full N-key rollover with mechanical keyboards), 4 x SATA 6Gb/s ports and 4 x USB 3.0 (lots of connectivity for hard drives and other peripherals).
Overall, I think you would be very happy with this board. The Dash V Pro is a reasonably priced board with a fairly extensive feature set and good overclocking potential.
