They are trying to sell that powerleap upgrade uder the pretense that you don't have to upgrade your motherboard so it will save you money, but have you checked the prices for the good one? It's just shy of $400!! You could get a brand new p3, Athlon xp and a brand new board and memory for that if you look around. What a joke!!!
Then again you could always get the $150 version which doesn't come with a cpu, or better yet you could get the one with the 800MHz p3 with 128mb of crap ram for $200, that is such a waste of money if you ask me. The system would still be slow because of the slow motherboard, not to mention the rest of your old components.
