CDR Info says Asus is preparing a dual GeForce 7800GT card. Months ago the company was already developing a graphics card with two 6800 GPUs but they cancelled that one because NVIDIA launched its GeForce 7800 GTX.
Currently Asus is getting ready to launch the EN7800GT Dual card that will feature two GeForce 7800GT GPUs on one PCB.
It is not clear whether using dual GPUs on the same PCB performs differently than a corresponding SLI configuration. In addition, such a card would be possibly have be longer and higher compared to to typical graphics cards and may not fit into typical computer cases. At last, if size is not an issue, then we should consider the dual-chip card solution as an interesting buy, as soon as its cost is lower that SLIs.
