Actual Effect of PCIE 2.0

I'm wondering if anyone knows the actual effect of putting a PCIE 2.0 video card (like the 9600GT) in a PCIE 1.0 mobo. Of course, I have heard all sorts of various things, but nothing too concrete.

If I had to make a pure guess, it would be that there would be zero difference at this time, as current present-day video cards probably don't use up even all of the "throughput" of PCIE 1.0 slots. But that is only a guess.

If anyone has any info regarding this issue, or knows any websites, etc...I would love to hear it. My apologies if this has been asked before, looked at the first several pages of the forum and didn't see anything...with other sites I skimmed through offering various takes on it. Thanks.
 
In general none of the current Videocards will exceed the bandwidth of a PCI-e 16x v1.0 slot. So basically; PCI-e x16 v2.0 slots aren't needed yét. Though perhaps the 9800GTX might get close, I reckon it still doesn't exceed it. The new 4xxx series from ATI and the 99xx series of Nvidia might get to the point that v2.0 might be handy (because of the vast amount of GPU power).
 
Did a little looking into this issue at tomshardware and it seems for the most part RIGHT NOW, PCIE 2.0 slots will have almost an identical effect as regular PCIE x16 slots with PCIE 2.0 video cards. In most every test (with the current high-end cards), there was almost no boost whatsoever. (like 1 fps) Obviously this is likely to change soon.

IMO, video card power is going to get pretty crazy here within the next year or so. Video card manufacturers have way more options with architecture to make ridiculously powerful video cards now. Supposedly PCIE 3.0 is estimated to be a 2010 release.

We have come a long way since Super Mario Bros. and Doom 1. IMO we have been at a relative graphics wall in gaming for the past 2 or so years. Kind of cool thinking about what the future holds. Obviously, something different has to happen in order to get to the next level of graphics...as we move closer to "real-time video realistic" stuff. To me, we will be at our current wall until this happens. I guess the only known hurdle (to me) left after that will be the progress of VR. (virtual reality)

Cool things for sure, regardless.

Well... I even then doubt if the 1 Frame boost was due to the PCI-e v2.0 slot(s). I reckon it's because the motherboard is just a tad bit better :)

(Or did they turn of the nForce PCI-e 2.0 controller somehow?)
 
I wouldn't even go so far as to say the new nvidia/AMD cards will use the increased bandwidth. The 9800gtx is no better than the 8800gts, and even the 3870x2 was tested in a variety of situations on both PCI 1.0/2.0 boards, high resolution w/ AA/AF, and results came back as neutral. So it was ultimately stuck on a PCI-e 1.1 bridge chip.

Mayhap the next generation after this coming one will see a small benefit, that's what I think.
 
I meant to say it comes close to the maximum of a v1.0 slot... Though so does the 8800GTX :) So that wouldn't matter anyway.
