Do you watch HD video (Youtube and the like) on your computer? That video is nearly 2MB per frame when recorded and at 30fps is 60MB per SECOND. It's compressed down about 5:1 for the internet so we are 8MB per SECOND... over the internet.
Any modern $800 laptop should handle these files just fine. I've got a 4 year old, high end, Dual Core Dell laptop, playing RAW video at 1GB per minute. No problems at all.
