Default What's Better? (PCI-E question)

SLI/CF in PCI-E 2.0 running at x8?
Or SLI/CF in PCI-E 1.1 running at x16?

x16 1.1

The update to 2.0 wasn't a huge improvement.

You might lose a frame or two, but no not really.

The only time it bottlenecks is on the really high end cards. (5870, 4870 x2, GTX 295, and 5970)

I don't think x8 vs x16 make that much of a difference either. I was just wondering which one would perform better, even if it is very minimal.

well its x16 1.1

You won't notice any difference with 8800GT SLI though.

Considering that PCIe 2.0 effectively doubled the available bandwidth over 1.x, I would think that a PCIe 2.0 SLI/CF setup @ 8x would still be faster than PCIe 1.1 @ 16x. But in all reality, you really wont see the difference between the two as no cards can saturate the available bandwidth.

I saw a review where they put a 5970 and a GTX 295 in x8 slots, and they each lost about 20%.

As far as what it takes to saturate an x8 slot, a 5850 is where it will start to hurt performance, with it becoming more noticeable with higher clocks. Anything more powerful loses more.

I have done a lot of googleing on this.

It also depends on the game too.
