Earlier, we revealed that Nvidia is planning to release

GeForce 9800 GT
  based on 55nm G92 core in July and now we learned a
little more details on this new card. The new 9800GT card is codenamed G92-280
and it is using a new P393-C00 PCB that supports Hybrid Power. There will be
256MB and 512MB GDDR3 versions that clocked at 900MHz and 975MHz respectively. 
The core clock has not been determined yet but it should clock higher than the
current GeForce 8800 GT which is at 600MHz default. Outputs are 2 x DVI-I and
HDTV.
