I'm going to max out my RAM with another 1GB stick from Crucial. On their website is a promotion that gives buyers of eligible products a free Official King Kong computer game. Crucial is a very easy-to-use website - you choose Apple, your model, and it shows you the compatible RAM choices. Well the 1GB stick for my APPLE iMAC G5 is listed as being one of those products to get a free King Kong video game. I noticed the only catch as I was checking out and noticed in my cart that the game is PC only!!!
