Is this hardware compatable?

I want to build a new system but I'm paranoid on forking that amount of cash without knowing that what I've chosen is going to work.

Please could someone tell me if this will work together or not.

Asus P7P55 delux
Intel i7 860
Corsair 2 x 2GB DDR3 1600MHz
EVGA Nvidia GTX260 216 core
