It's not going to happen either, as the Gigabyte card requires an SLI system even though it only needs one slot. The forum post on Hardware Analysis is just a pipedream from an uninformed user.
That's exactly what I meant, dual GPUs and dual video chipsets on one video board (or single chipset if they apply a configuration similar to NF4 Ultra). The problem is not finding 4 PCIE slots on a LT, but rather fitting a board with dual GPU/chipset onto the size of a board; and even more importantly, the thermal limitations of a LT, which already have some trouble in fitting a single 6800/X800 into its chassis while running stable for long periods of time. How many graphics cards are really irrelevant in this case, since 2x2 graphics core will function in the same way as 4x1, they can implement in whatever way that is convenient for them.
Have you seen the size of the latest 6800 Ultra, they are literally half the size of an ATX mobo; I can imagine how a dual GPU card will look, even less that it will be able to fit onto a board that can fit into a LT PCIE slot.
This will either require enormous chassis for a laptop, or miniaturization of the graphics technology + graphics cores that run under lower thermal envelope and power requirement. And even a Dual GPU system will drain the current generation of batteries in 1 hour or less. Such as system has absolutely no mobility, both in terms of weight and power consumption, it would be a joke to call them Laptops.
Edit: NV50, NV48, NV45 are names of graphics cores, they are not the names of graphics cards, which may use one or more of them, and clock them differently in different grade cards.
