Radeon 9800, Continued
The most obvious visual changes compared to the 9700 have been to the board layout. The Radeon 9800 board is slightly longer, making it look less cluttered overall. The auxiliary power connector now uses a four-pin Molex plug, which feels much more stable than the previous three-pin floppy power plug found on 9700 boards. The new review board also sports a new heat sink/fan combination.
