Great review! A first-time PC builder here by the way. I thought about building 2 PCs: 1 for gaming and the other for general internet use and watching videos. I really don't wanna spend too much on electricity bills by using an overclocked, GTX 770-powered, watercooled system just by checking facebook, when a stock system with just an iGPU is enough. I searched for single-PC options and came across this Gigabyte GA Z87X-OC, and particularly got intrigued by its OC-PCIe switch feature. If my understanding is correct, I can disable my graphics card and save around one-third of my power consumption by just a press of the aforementioned switch. It's probably like Nvidia's Optimus featured in laptops, except this time you do it manually.
Question is, what is the proper procedure? Is there a correct sequence/proper time to switch? Can I simply disable the video card by pressing the OC-PCIe switch in the middle of a windows program? Or should it be during boot up? Also should I remove the video cable from the video card I/O then connect it on the motherboard I/O every time I press the switch?
Sorry guys I'm definitely a newbie here. Not really too concerned about overclocks in the near future. I'm really more into finding ways to save on electricity as I only get to play during weekends and let my mom and sis use the machine majority of the weekdays. Thanks in advance.
