a couple of pictures of some of the upcoming Radeon HD 3870 cards today. The first one is from Sapphire and the card follows the reference design in every way.
The card is apparently clocked at 775MHz for the core, 2.2GHz for the memory and has 512MB of GDDR4 memory. You can check out the picture here
The second picture is a bit smaller, but it's from an Australian retailer and it's supposed to be a picture of GeCube's Radeon HD 3870. This card is aparently clocked at 775MHz for the GPU and 2.4GHz for the memory.
TweakTown scored this picture and the card is meant to retail for AU$358, which seems quite expensive, but as with Europeans, Australians get ripped off. You can find the picture here
