dear Cube list, I am only new to the cube ownership, but am already trying to understand all the upgrade options. it seems there is a lot of talk on the list about replacement graphics cards. Does that mean the stock graphics cards is very slow, or is it just a desire to move onward and upward. I have no desire to play games, but may watch a few movies and figure this may be relevant. If I wanted to replace the card, which is the best option without having to install a fan (I kind of like the fact the cube is silent). or is it essential to have a card with a fan? many thanks in advance Chris
