Yes, everything finally went right, and I'm happily typing away on a new computer. And I'm having a blast in the free copies of Far Cry 2 and Assassin's Creed that came with my parts (tomorrow, I'll get Team Fortress 2 at half-price).
I've switched back from Chrome to FireFox 3, since I can handle the resource-hog-ness of it. However, I have installed several plug-ins to make it more familiar.
