I use a lot of these motherboards, as in over 100 a year. They work great for general workstations and consumer builds, and I've only had one DOA board out of a couple hundred total.
They lack in some features, such as no PCI slot and only one PCIE slot. The video slot works fine and the onboard video connection works fine also. Gigabyte recently came out with a competing budget micro-atx board with a gigabit LAN hookup and I'm hoping the ASRock will get a new revision with this and USB 3 at some point, but it's not really a deal-breaker yet.
While I have seen these used to play games, keep in mind that this is an entry level budget 1155 motherboard, it isn't a powerhouse, don't expect it to be.
If you want a full-featured BIOS and solid construction with longevity and a low price point, these are a great choice.
