Bigbruin.com has posted a review on the ASUS EAH3870 TOP Overclocked Radeon HD3870 Graphics Card

As the big brother to the HD3850 TOP card I expected it to perform about 10-20% better, and in general that is about what it did. It offers solid performance in today's demanding games without draining you of the extreme amount of money that the high end cards will set you back. And while the card may be overkill for the typical home theater setup, it does offer all the features you would want there as well.
