@happy:

Because the performance increases with a better card, irregardless of link speed. However, the diminishing returns curve is steeper. Here's some reading:

As you notice, there isn't always a linear increase, and the solution isn't as simple as you think it would be.

You had the link, those are old 8800s and you can already see the bottleneck effect. Of course there will be best cases, but on average you won't get more than 20% out of those babies.

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:

http://forum.notebookreview.com/gaming-software-graphics-cards/418851-diy-vidock-experiences.html

And here is the link for the original scores:

http://www.overclockersclub.com/reviews/inno3d_gtx460_1gb_oc/15.htm

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:

http://www.anandtech.com/show/2951/nvidia-s-next-generation-ion-announced-optimus-a-16-core-version/2

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.

hmmm, the only question then is what is the difference for your usage of gtx 460 768 vs gtx 460 1gb. 1gb has slightly higher clocks but they overclock to nearly identical levels, possibly slightly favoring the 768mb card. Generally speaking that 1920x1080 I'd strongly recommend the 1gb card. but are you going to max out the card's ram with it limited to 1/2 speed anyway? What is 1/2 the speed of a gtx 460? nothing that needs more than 768mb of ram most likely.

Well, because I won't be able to run most games at playable rates @ 1080p, I think that a 768 will suffice. Saving $ is nice too, especially with that awesome deal you caught my attention to. :)

Since I have the same computer (just with a tablet screen) and slightly upgraded CPU as one of the guys who tried the optimus tweak, I should see a 15K 3D mark score. So, I'd be getting 75% of the performance of a 460 GTX on my laptop; which will be great.

I'm thinking I can even put the entire thing in a plastic shoe box and cut/drill holes for ventilation and cables. All in all, I will have an ultraportable convertible tablet PC + a semi-portable gaming system when I need it. It isn't as sleek as a gaming laptop, but I wouldn't use the gaming features most of the time. Because portability and single computer use is important to me, this is a great solution.

glad i could help, because this is a seriously. cool. idea.

please give us some pics of actual gaming when the system is all set up!
