Solution
Considering the two graphics cards that you have linked to:

- If you're planning on using two graphics cards in SLI or CrossFireX mode then your only option is the EVGA P67 SLI Micro 120-SB-E672-KR if you want to maintain maximum performance from both graphics cards.

- If you need an IEEE 1394 (a.k.a. FireWire) port your only option is the EVGA P67 SLI Micro 120-SB-E672-KR.

- If you want to use the integrated GPU, on the Sandy Bridge CPU, then the ASUS P8Z68-M Pro is your only option.

- If you need the legacy PCI slots then the ASUS P8Z68-M Pro is your only option.
