Josh spotted a great deal this morning on NewEgg for the HIS Radeon HD 5870 (H587F1GDG).  You can grab the fastest single GPU graphics card on the planet for under $400, whether you are in the U.S. or in Canada … there doesn’t seem to be a, so we can’t claim the sale is North American wide.

For those readers in the states, you can head right here for a $379.99 HD 5870 with free shipping.

For fellow Canadians, the price is just a little higher at $398.99 and it seems you will have to fork over a bit for shipping.
