yeah it should all work pretty well together. It should work with any current gen i-series chip.
FYI - your two graphics card will bottleneck because if you run them in SLI, the board will go from PCI-E x 16 to a PCI-E x8 since there is only 1 full x16 socket out of the 3. But don't worry, the difference is less than 5%. So it won't be something you will notice. Just a little heads up.
