It's definitely not royal power, but some people dislike replacing PSUs at a whim. (Of course, having the right purchase does negate it completely)
The Booster wasn't meant to supply all 12V+ wattages, just part of it. But I'd say a good main PSU would be a better insurance overall.
Xello, stick with 8x. You'd be lucky that even half of the DX10 games support that.
