GTX 580 Tri Sli x8... - Page 2

post #11 of 24
I know I'm new and all but there is hardly a decrease in performance at 8x over 16x.

Yes 16x would be preferred but it isn't going to make a substantial difference.

There is a difference between handling it, and allowing it to generate 5000 FPS. All CPUs bottleneck GPUs, thats just a fact of life. Where the bottleneck appears is the most important thing. Is it at 55 fps or is the bottleneck at 130fps.

On topic, there is virtually no love lost at x8.0 PCI-E, infact, if you overclock the gpus, you will more than recuperate that % lost.

For benchmarking purposes, you won't be beating people with 3x 16.0 PCI-E, not that that is a huge deal.

Go for it OP. The performance increase of adding a third card will be far greater than the performance decrease of running 8x pcie

It shows actual data regarding the difference in pci-e slot width. It's like 1-2% percent, 8x vs 16x at 2560+ res.

the 5970 or 5870x2 cannot even use a full 8 lane slots bandwidth. whats the question again? bc x16 is the highest number, everyone thinks its the only acceptable solution !?

You don't play benchmarks

In my mind benchmarks are just to make you feel good about your awesome hardware.

You'll only be about 1-3% slower than an x16,x8,x8 setup. But you may bottleneck, so you may not even see a difference between yours and x16,x8,x8.
