Back when creating vZilla, I decided to standardize on this same motherboard I've become quite familiar with, for a gaming system project. With ESXi 5.0 running on one system juggling many OSs, and another system to run just Windows 7 x64 SP1 Ultimate. Nice bonus is the convenient comparative look at the motherboard's features and performance, while operating in two very different scenarios, concurrently.
Once again, the trusty ASRock Fatal1ty Z68 Professional Gen3 has served our family's needs quite well, coupled with a nice MSI N560GTX-TI Twin Frozr II Video Card for excellent framerates, even when playing SCII at 1920x1080 and streaming live with XSplit. The young gamer dMBoyo is leveraging this system's speed quite nicely, as you can see from his streams and Grand Master ranking.
And the start up time for games, wow, that 3rd generation SSD makes a big difference, caching that nice big and convenient 2TB RAID0 C: drive. 40 seconds to start SCII on a laptop, 25 seconds on a single 1TB drive on gZilla, then down to about 5 seconds currently with the below configuration with a 3 drive RAID0 and Intel SRT SSD caching enabled.
