Though still quite speedy and more than adequate in most photographic situations, Corsair's 40X card will likely lag behind the Extreme III a bit if you're doing a lot of TIFF or raw shooting. Plus, Corsair's excellent reputation as a high-speed system-memory company gives it a little extra street cred.
