Deej, I think you could get a bit carried away chasing horsepower. Having said that, I think it really depends on your riding. Take Jools for example. He has a similar amount of power and more than holds his own in the fast groups and on the rideouts.
If you don't have the latest Japanese missile, then your mate who does is always going to go past you on the straights. Unless you get a Desmosedici RR or a 999R and spend money on it then you are always going to be at a horsepower disadvantage. In my mind, you'd be much better off getting an 853 kit from someone like
Sigma Check out the dyno charts on the Sigma website. Have a chat to DC, he's had it done.
Your biggest speed advantage is a nice strong midrange, with plenty of torque to fire out of corners with and your ohlins suspension. Anyone can go fast in a straight line.
