Everyone always says that I should get RAM from a 3rd party instead of Apple and $500 for 2 more gb seems pretty high, imo. I'm a little wary about doing so, because once I plugged in some ram to a motherboard and it went bang and melted to the board, destroying both the board and RAM. Since these parts were from the same place, I was cool. But now I'm paranoid about ram. Would Apple (with applecare) cover damage from 3rd party ram? From looking at an applecare contract it seems like they will not. Are there any retailers that would replace all damaged parts, not just the ram I bought from them? If not, I think i'll just fork over the extra 5 bone. Btw, the 8800 GT is best for games, and worth the extra 2 bone, right? (I know it isn't a gaming system, but it's nice to be able to play the occasional game) And am i correct that I only need to go 8-core if i do stuff like video? I often work with huge excel files and such, but 4-core's gotta be enough, right?
