Head in sand or bite the bullet?

There is something funky going on with the display on my laptop, ranging from weird purple pixel patterns showing up on video to the monitor blinking on and off and going completely black every now and then for a few minutes. The Apple Care dudes think it's the video card.

So I can ship if off for repairs and not have a computer (except for the one in my office, where I can't do work without all manner of humanity interrupting me) for a week or I can hope for the best until I can actually go for a week without a computer, like during December break.

Thoughts?
