I'm still strongly considering buying a 2.9 GHz Llano. The Fusion A8 is still faster than the old Q8200 that I currently use for my music production station, and paired with the nVidia 8400 GS (fanless!) that I also just bought, I think that the whole system will perform pretty well.
AMD is still kicking butt when it comes to price/performance. True, Intel still is tops, but I believe that this is changing. Plus, if ARM processors ever come out for desktop PCs, I believe that both Intel and AMD will have some problems.
Folks like myself, who are looking for low-latency, high-performance, and low-power alternatives could do a lot worse than by going with a small instruction set chip.
