Impressive Speed: With auto focus speeds as fast as 0.16seconds, the F800EXR delivers outstanding high speed shooting capabilities, up to 8 frames per second (fps) at full resolution (11fps max speed at medium resolution), and full HD movie capture at 1080p (30fps) in stereo.
The only way I have been able to max out both cores is by playing a H.264 and HD DivX files at the same time. (If I try two H.264 files QT crashes) The 2.0 Core Duo has more than enough juice to decode any HD files I can find for my computer.
