The X58-USB3 does also support multi-GPU configurations by either ATI or NVIDIA. This provides not only the ability to be more powerful but also gives the diversity of being able to use which ever brand you may prefer or have on hand. When it came down to overclocking, the motherboard didn't really give me any problems getting up to 3.8GHz with the i7 920; however, that clock speed seems to be the maximum that my chip can reach as it is a C0 stepping.
