Too vague.

Here are some numbers.

http://74.125.93.132/search?q=cache:...&ct=clnk&gl=us

Power 1-sp 3sp-L 3sp-1:1 3sp-H 6sp-24 6sp-19 6sp-13

50W 96 90.6 93.4 87.3 94.2 94.1 92.1
100W 97.3 92.8 95.7 90.9 96.2 96.4 94.9
200W 98.1 94 96.9 92.9 97.4 97.6 96.9
400W 99 95 97.9 93.9 98.1 98.4 97.8

I doubt you'd feel the difference between a "$5k bike" and a "decent" fixed-gear.
