We found Sapphire's HD4870 X2 2GB GDDR5 listed for €433 on two sites. No surprise price-wise, and as expected the GDDR5 flavored version comes first. The card runs at 2x 750MHz and 2x 900MHz for the core and memory. It has a 2x 256-bit memory interface, 2x 800 stream processors and 2x 40 texture units. We're still not sure about the power consumption or availability dates, although initial reports claim it should be widely available in the last week of August. Nvidia's 55nm GT200 is expected in September.
