I been recently searching about AMD chipset based motherboard in the search for the adequate product for my almost non-exist budget.
So... I read various reviews, forums and such...
I was thinking in the 780G, maybe the GA-MA78GM-SH2, because the price/performance match what i was after...
But today, out of nowhere, a significant number of models based in the chipsets 740G and 780V were released.
And the range of makers were high: MSI, Gigabyte, ECS, Jetway...  
So my questions is: what are the pros and cons of this 2 chipsets against the 780G?
Of the big amount of models there is one how offer a best "bang for the bucks"  that the GA-MA78GM-SH2?
I need more info about this "new" chipsets, because every dolar count.
Thanks in advance.

Think of the 780G as the "flagship" model with all the goodies enabled and think of the 780V as the next in line, missing some of those extras, and finally think of the 740G as the "low-end" dont touch it ever.
 
Basically stick with your guns, the 780G is a home run hit for AMD and i suggest you buy the Gigabyte 780G as that has gotten great reviews.

The 740G is essentially an re-badged 690G with a new south bridge, it's not worth buying.
 
The 780V is a lower-clocked 780G, so it is definitely worth building a system around.
