I would go with a better mobo if you think you'll ever be interested in SLI or Crossfire. It's says it has (2) PCI-eX16 slots but on the Asus Website P8P67 webpage it says:
*The PCIEX16_2 slot shares bandwidth with the PCIEX1_1 slot, PCIEX1_2 slot and USB3_34 connector. The PCIEX16_2 runs at x1 mode by default for system resource optimization.
- 1 x PCIe 2.0 x16 (single at x16)
- 1 x PCIe 2.0 x16 * (max. at x4 mode [Black])
- 2 x PCIe 2.0 x1
- 3 x PCI
That means the 2nd PCI-eX16 slot is a PhysX slot or a crippled slot.
The slightly more expensive boards should allow the (2) PCI-eX16 slots to run at 8X/8X when both are in use and I've seen a few models that support 16X/16X but they cost Top Dollar.
This is the cpu you want to get.

Edit: This looks like a good board but Newegg doesn't have them in stock yet.
I'm waiting for the EVGA P67 Classified to be released
