GTX 580 Tri Sli x8...

post #1 of 24
Thread Starter 
Just got a new motherboard and I'm thinking about running a third 580 just for kicks. The problem with the motherboard is that it runs x8,x8,x8 in Tri Sli. How much (if at all) would the setup be bottlenecked by running at that speed? I see that Tri Sli scales pretty nicely on most games...

I believe it's like 4% decrease or something I read with the speed drop.

What speed do you have your processor running at, that is going to bottleneck before anything else does.

yep 5% less.. that's what I read. But who cares 3 580's would look INSANEEEE!

My cpu is at 4GHZ right now and that's probably where I'll keep it. From what I've read the 980x doesn't bottleneck the 580's but I could be wrong.

If you were running it stock with 3 580's it would. Don't get me wrong it's a great processor. Even with it running at 4Ghz I would have thought that it would still end up bottle necking at some point.

At 4.0 you shouldn't be hitting a bottleneck on the CPU and as far as the tri-fire at 8x you will only see minimal loss 4-5% the 580s scale extremely well I'm planning a tri 570 setup in the near future

Someone, I think defoler, told me his 980x (4ghz+) bottlenecked 3 470's.

Well then it's probably not worth discussing at all if the flagship processor by Intel can't handle it nothing can. Oh well, I am sure I will still see very noticeable gains at 2560x1440.
