I am in the process of replacing some suspect parts in my computer and the first one up is the motherboard. I am planning to keep my current processor and ram so I started looking at socket AM3 boards. I noticed a sizeable price range and reasoned some of it is do to the chipset used. I had payed no attention to them in the past so I deciede to try and get some understanding. I eventualy came a cross this article.
the 970 and 990FX chipsets are the newest from the AMD side, i would reccomend getting a mobo based on them, but if you plan to use mATX form factor, you going to have to use the 880G chipset, which is still an alright setup
