how many 7 segment LEDs can a arduino run?

Hey guys, it doesn't look like this was ever answered proper. I have a similar need:

I need to run 3 separate 8-segment LED displays independently. Meaning, 1) Stopwatch Timer 2) Temperature 3) Calculation

Is three of these overkill? Sparkfun 7-Segment Serial Display
sku: COM-09230

Can the Arduino handle all that?

Thanks!
