What do you mean by "ability to CrossFire or SLI with a GPU"? You can't CrossFire or SLI with the Intel IGP that resides in the Sandy Bridge CPU.
Current Sandy Bridge motherboard chipset H67 disables the IGP and its related functions like Quick Sync when a discrete graphics card is plugged in. The P67 chipset doesn't allow you to use the IGP or Quick Sync at all.
SLI requires that the GPUs be SLI capable and be the same model.
CrossFireX requires that the AMD GPUs be CrossFireX capable.
