Amd A75 vs. Amd A78 chipset

So I'm building a pc for the first time; its going to be a cheep multipurpose pc. I'm currently down to one of two motherboards for the build and don't quite understand the different amd chip sets. The two boards are a GA-F2A75M-HD2 and a GA-F2A78M-HD2. are the chip-set differences just a different manufacturing thing, or is one really better than the other. I'm planning on using a 6600k a8 processor. which board would be best for this processor, and have the ability to upgrade CPU later. Additionally I may want to overclock the CPU to 4.2ghtz or so.

Just in case anyone was wondering, the difference in the chip sets, is just age. The amd A78 chip set is simply the newer version, which is Microsoft certified for windows 7. While the A75 chip set isn't rated past windows 7.
