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.
