I've considered i3, and the power numbers do look good, but performance on some benchmarks I've found looks..."unpredictable," and frequently less than one of the considerably cheaper AMD offerings. I'm actually planning to build a very portable, multipurpose machine that I intend to be capable of playing moderately demanding games; GPU may be as low as a HD5670, more likely a HD5750. The case will most likely be either a Sugo SG05 or a Lian Li PC-Q08. I will probably start a discussion thread about this build fairly soon. I'm waiting for a mini-ITX board that supports AM3 and has a PCIE X16 slot on it to become available; Sapphire has one that isn't here yet, and I believe Gigabyte is also about to release one.
