I really found myself pleasantly surprised with the GIGABYTE A55M-S2V and just the A55 chipset in general. Considering the price tag of the board coming in at $74.99 US, paired with an A6 or A8 series APU from AMD, you can get some really nice performance out of the board.
If you want to kick it up a notch, you could throw a HD 6670 into the mix and combine with the onboard GPU built into the APU; you could get some great performance thanks to the ability to CrossFire both the APU's GPU and the physical GPU for even more performance.
What makes the A55 and A75 so different is the fact that the A55 lacks USB 3.0 and SATA III. Sure, they're great technologies, but, are they worth spending more money on? They are if you have a SATA III drive and USB 3.0 devices. If you don't, then it's not worth spending the money on.
For $74.99 US, you're able to get near identical performance to the more expensive A75 chipset in most aspects. You also get great overclocking potential, and really that's one area that stands out so heavily for the current A6 and A8 series Fusion based processors.
There's really little to complain about when it comes to the A55M-S2V. Sure, the package is small, but the board is cheap. Sure, the baby blue setup isn't the nicest to look at, but the board is cheap and the board is cheap.
To be honest, I'm not too sure why AMD and their partners haven't promoted the A55 chipset more. USB 3.0 and SATA III are both fantastic technologies, but if you don't' use devices based on that technology, then it's just not worth paying more for it. Especially when you get "system" performance that is near identical to the more expensive A75 chipset. Both chipsets have a clear market and I think we need to see more companies promote the A55 one. Sure, it might be a bit more "boring" than the A75 chipset, but we like to cover all aspects of the market and A55 based boards seem to offer us really strong price.
If you don't care about USB 3.0 and SATA III, want to save some bucks and want to enjoy the benefits of the Fusion platform from AMD, the GIGABYTE A55M-S2V is an awesome board at an awesome price.
