nVidia 9800GX2

The 'next gen' nVidia card (9800GX2) is two G92 GPUs in a single package running in SLI.

It is basically an SLI of the current 8800GT/GTS512 cards (G92 GPUs, 512MB ea) on two PCBs mounted to a single PCIe 16x interface.  It will require two PCIe (SLI compliant) power inputs and cost about $450 (or $50 less than two 8800GTs in SLI).

Based on the 'success' of the 7950GX2 some people are expecting this to be a flop.

Looks like I will be getting a 2nd 8800GT when my tax check comes in...
