Performance increases with a better card, irregardless of link speed. The greater the resolution, the greater the reliance on link bandwidth. For example, playing a game at 1200x800 with a 9800 GT on a
x1 or a x16 PCIe connection would perform the same (given that the other components are the same). Now replace that card with a 460 GTX, and you would have a higher framerate. (yada, yada, you don't need to retort back about the human mind's ability to discern FPS after 60) If you don't understand something, that is fine, just ask. But don't simply speculate. I honestly don't know how to make this any clearer to you.
I trust the benchmark numbers from multiple people, not assumptions. Here is the link for that:

And here is the link for the original scores:

You will notice that people are getting roughly 50% performance with the exact same laptop. With the optimus tweak enabled, some users are seeing 75% of the performance:

Essentially, there is some sort of special sauce that Nvidia is using for their ION GPU, that just makes this work. Link here:

This benefit extends over to this "hack" simply because the ION computers use the Intel HD chipsets, and I know this works because several people are posting results through accepted benchmarking suites. Couple that to the fact that Nvidia specifically states that this will work, though they won't release how.
My question was rather simple: 460 vs. 560; and I've decided to go for the 460. If I doubted that this would work, I would have asked about that and not what card I should get.
The ViDock solution works. I've tried it: I've seen it work in real life. It certainly isn't a placebo, because I've used. I've already done my homework and I've seen the results others have had.
I've already tested some games with both the 9800 from one computer and a 260 from another and saw a significant increase in performance when switching between the two. I could even borrow a 5770 from a buddy and try that. However, I'm satisfied with my findings, and am ready to purchase a permanent solution.
