Kernel Task slowing down Everything

Suddenly this morning, a Kernel Task using over 700 MB RAM is slowing down my Mac Pro. Saving in Photoshop gives the wait cursor, and slow progress bars. I have 8 2.8 GHz cores and 10 GB RAM! What is going on? Mountain Lion, in spite of a carefully prepared clean install, has been buggy with numerous glitches. The most annoying Mac OS I can remember since OS 9.

Mac Pro, OS X Mountain Lion, 8 x 2.8 GHz 10 GB RAM, Radeon 4870

Hi everyone!

Seraching and searching everywhere, I've probably found the explanation for this problem:

The Intel HD 4000 graphic card consumes up to 768Mb from RAM. That's why kernel_task is using this amount of memory.

Hope this helps.
