while choosing a motherboard you gotta decide on few things as below;
0. what kind of cpu are you going to use
1. what kind of case are you going to use
2. how many pcie slots do you need
3. what kind of outputs do you need
4. are you going to use any motherboard integrated gpu/sound/ssd etc...
5. are you going to overclock the system
6. SLI or CrossFire setup
7. what color do you like
so as a so called "gaming motherboard" you actually need at least
1. intel or amd based mobo on preference
2. usually a mid tower or full tower is selected which results in choosing atx or micro-atx motherboard
(if you are going for small tiny stuff you may need itx or slim itx motherboards dependent on case choice)
3. number of usb's (3.0/2.0), number sata's (sata3 or sata2), firewire, thunderbolt, optical outputs, sound channels etc.
4. cpu integrated / mobo integrated gpus, mobo integrated m-ssd's, number of sound channels or if you need discreet soundboard you may need extra pci channels
5. if you are going to overclock the system, make sure that it supports full voltage and multiplier controls plus quality copper board (also called pcb) to endure high voltage and high temps
6. if you are going for multiple graphics card setups you may want to get at least 2x 16xPCI channels to support your both gpus or more channels for more gpus...
(also keep in mind micro-atx board generally doesnt support more than dual gpu setups)
7. i like blue ! i hope you also do
so... there is basically no gaming mobo, but theres for sure a mobo for your gaming setup.
