When you compare both MSI H 87 is better, for gaming since it has 2 pci x 16 slots you can think about SLI/ xFire the Asus board has 1 slot for GPU. Both boards support USB 3.0 and also can support upto 32GB of RAM, but when it comes to gaming you do not require above 8GB as of now.
I would say go with MSI among these 2
