How important is ISO 3200 and 1/8000 shutter speed?

[Loupey]

A few real-life examples at what I consider "high" ISO's (all at ISO 1250).

The first street scene (of the security guards taking a snack break underneath the tent) was extremely dark - dark enough that I could barely see the bikes just behind the tent. But was still able to get the shot at 1/45s, f/2.8, using ISO 1250.

Lots of ways to get the job done. Don't let the spec's alone dictate your decision. Would one base the maximum speed of a minivan as the deciding factor for a purchase?
