The ASRock 939A8X-M does not support onboard graphics. Any system build that uses this motherboard therefore requires a separate graphics card, or a processor that has a GPU on the same die, such as AMD APU processors. There are 0 PCIe x16 slots on this motherboard. The ASRock 939A8X-M does not support multiple graphics cards via Nvidia SLI or AMD Crossfire.
The ASRock 939A8X-M has 8 USB 2.0 slots but no USB 3.0 slots. While USB 3.0 slots are so far by no means necessary, and with a plethora of USB 2.0 peripherals to choose from, the USB functionality on this motherboard should be fine. If planning on building a new system, a motherboard with USB 3.0 is likely to have a longer life cycle, however.
