Which memory card for my new A-700?

FlyNavy

What is the difference in performance between the:

SanDisk SDCFX3-008G-A31 8GB Extreme III CF Card
and the:
Crucial 8Gb Lexar Media Professional Udma 300X Compactflash Cf8Gb-300-380

Would I need the Lexar 300X to utilize the 5 frames per second function?
Would I be happy with the SanDisk which is about 40% less $$$?

Would you recommend the LCD screen protector?

Here are the links for the 2 cards.

While not for an A-700, but for a A-800 perhaps this might help.
