CF speeds

Probably discussed prior but a search didn't turn up a specific answer.

CF speeds and D2X use.
I've been perfectly happy with a couple of run-of-the-mill Sandisk basic 1gb CF's from the Costco up the street.

Question: Who of you feel the need for faster than basic speed CF cards.
Cost isn't that much different and scrimping here isn't a big deal, but really, does it ever matter if I don't do sports much and rarely would shoot more that a couple of 10 round bursts?

Thanks.
! B&H saws D2X shipped...here Friday!

 

Highly helpful link, the Galbraith was.

I want 2 2GB cards

To summarize for my purpose:

At amazon today:
Sandisk standard 2gb $138 "standard speed"
Sandisk Ultra II 2gb $180 about 6 times faster
Sandisk Extreme III 2gb $220 about 8 times faster

A little more money gets a lot more performance.
If you never fill the buffer it may never matter.
