We saw an interesting graphics card at Galaxy today. Their latest
9800 GT uses a mini-HDMI connector instead of a normal sized one.
This gives Galaxy the freedom to put dual-DVI outputs on the card, instead of the DVI+Analog most other manufacturers use for space reasons. Should you plan to use a fullsize HDMI connector, an adapter is included with the accessories. Such a concept could be used on all other HDMI cards of course, it seems to me that Galaxy is testing the market with this 9800 GT design.
Another cool idea is this GTX 285 that uses a passive heatsink on the card itself. Actual airflow is provided by a second card that uses a PCI-Express X1 connector.
Last but not least, we spotted this single GTX 295 reference design. According to NVIDIA there is no set NDA date, board partners are free to sell cards any time they receive stock of production boards.
