Which video cards saturate PCI-e 1.0?

[goosetheforce]

Hi all,

I remember reading some time ago that new video cards were not yet able to saturate the bandwidth of PCI-express 1.0. I don't imagine that's still true.

My mobo has a PCI-e 1.0 (1.1?) slot. If I bought, for example, a Radeon 4890, would I only see a fraction of that card's throughput?

No card requires that much bandwidth. The card will perform about 99% like it should. Next gen ultra high end cards (x2) might start to feel light bottleneck
Hopefully your slot is running x16.

well yeah i dont think anything bottlenecks that bus yet. also in future generations, you can just run SLI if u have it so u keep getting good performance

I think that the 4870x2 and GTX295 might fully saturate a PCIE-x16 v1. No single GPU card will though, so I wouldn't worry about it even for a card as powerful as a 4890 or a GTX285.

Thanks for the helpful replies. Just to clarify, this is regarding a PCI-e 1.0 x16 slot versus PCI-e 2.0 x16

yeah
