segun lo que estuve mirando la motherboard parece compatible con el procesador
The Core i7-870 processor does not include a graphics engine. To use it, you will need to have an add-in graphics card installed. There are a *lot* of compatibility issues that exist between motherboards this old and new add-in graphics cards. I have used a NVIDIA GTX 750 ti graphics card with P55 motherboards, but haven't tried anything newer than that.
Hope this helps,
