Well I do have a few recommendations for you especially if your going for a light to mid range gaming rig.
A nice standard and reliable board with a good price tag is this one - Click Me! I've use MSI boards in the majority of the standard and light gaming rigs I've built, it's not a good board for playing around with overclocking but will run a socket 1155 i3 of any sort without issue.
It did catch my eye that when you stated you were looking for a board for either CPU that you did not have the CPU yet. If this is the case I may like to point some recommendations towards AMD APU motherboards and CPUs, the reason is because you are running a 6670 which so happens to be the highest card you can pair with an APU to get dual graphics mode, its like a cost effective crossfire. In terms of CPU power an i3 has more of a kick then an APU but as for graphics performance you would get 50% increase easy gaming performance for the same price. If your interested I'll post a few recommended setups.
I really like all the features on the board such as all SATA 6.0Gbps ports and 4x USB 3.0 connectors along with native DDR3-1866 support, but the main reason why I push for this is because of the nice boost you'll get in games.
Well the thing is, I dont know much about the whole difference between intel and amd but i do know about intel, so using amd seems wierd, mainly because i understand the whole i3 i5 i7 and all of that, but then i look at amd and have zero clue about anything about it, but if you would want to explain i would love to learn
Yes, Intel CPUs are most definately faster the AMD. But light gaming is not based around CPU power, A CPU becomes a bottleneck for graphics performance when you get into graphics cards upwards off 200 dollars. Having an i3 is a great CPU but you will be limited as to your gaming performance with only a 6670, Going with a A10 lowers your CPU performance but you will get better gaming performance with dual graphics processors.
