[quote]Can we assume that the PCI-E x8 lane can actually reach its theoretical maximum bandwidth?
I think the bandwidth of the PCI-E is the smallest of problems here. With resolutions as high as 3x 2560x1600 (7680x1600) the power of the computer will become a problem a lot sooner, considering that you can't even use SLI. Not to mention that there aren't many people that even have 3x 30" monitors :P

PS. I did some recalculating, the actual bandwidth needed for 2560x1600@60Hz should only be about 1GB/s.

That what I heard of was that the f. g. the performance with 2 8800gtx at GTR2 at 3 x 1600x1200 was worse than 3840x1024 with one 8800gtx card and TH2go.
Is it true, if yes what is the reason when it is not the pcie interface ?

SoftTH doesn't support SLI, so the in both cases the game is rendered using one 8800gtx. What you are comparing is a game running at 4800x1200 vs 3840x1024, the latter is a smaller resolution so it runs better because of that.

I'm wondering if the PCI-E bus would ever become a limiting factor.
I don't know how fast the PCI-E bus is in practice or if there is some overhead that is needed besides the image.
But I am quite confident that the PCI-E bus won't be a limiting factor in any case.

You mean the second 8800gtx is not rendering though she is connected to one 1600x1200 screen?

SO it does not matter what the second vga can perform?

Correct. The second GPU during SoftTH use simply receives a fraction of the image and disaplys it on the connected monitor. The primary GPU does 100% of the rendering.
