The ION is an Nvidia Graphics Adapter that is similar to the 9500m (much better than standard on board video), the Atom 330 is 1.6GHz DUAL CORE, I am using one right now.  I havnt tried PRoject 64 on it but it plays MAME really nice, I am having issue with Killer Instinct but I dont think its the PC.  I run Team Fortress 2, Fall Out 3, Left 4 Dead, Call of Duty 4 on it and its a NETBOOK.  ASUS 1201N.  The ION also can do true 1080P HD Video where standard onboard video can not get close.  the ION + 330 combo is great, use at least 2 GB of RAM though.  HIGHLY RECOMMENDED.  And if it is 200 bucks and it is ready to rock and roll out of the box, it is a great deal in my opinion.
