I'm from the "more power is better" camp. In reality, though, I've never felt I could justify the cost for a high-quality amplifier rated at more than 200 wpc.
Would I LOVE to own the 1000 wpc Boulder 2050 monoblocks? You bet! Is it in my budget? Absolutely not!
As a point of reference, I think my 200 wpc McIntosh MA-6900 drives my Vandersteen 3A Signatures about as far as they can go. Since the Mac has the power meters, I can, and do from time to time, monitor how much juice is being put out, and it RARELY draws beyond 100 watts. I've NEVER seen the meters top out at the full rated power level.
It really depends on the size of your room, desired volume, and type of source material. If you have a really big room, then I'd go with as much power as possible. At some point, though, the 913's will be your limiting factor.
