Seems like 2 cards don't even need the bandwidth, who will really benefit other than the tiny percentage of 3 and 4 card users?

Toms did an article a while back about PCIe 16x, 8x , 4x and 1.0 and 2.0 gen bandwidth, it would be good to see this again for PCIe 3.0.

almost no performance difference... already expected that 304.48 drivers were the awesome stuff, those drivers increased a lot my performance, specially in 3D Gaming

We won't see PCIE3 useful until the next gen GPU's come out. 1.5% differences between PCIE 2 and PCIE 3 makes no difference in gaming, only if your into really high end benchmarking/world record breaking.

the diference between PCIE 2 and PCIE 3 is very small when you have one or two cards, but what about people like me who have 3 card (soon i will have 4) , will this patch make a noticiable diference?

Did you actually, well, read the article?

"Going in to installing the patch, I knew the only true performance benefit I would see with PCIe 3.0 would be with either a 3-way or 4-way SLI setup, so I wasn't expecting much to change on the test results."

Well, it doesn't hurt to have too much bandwidth.

Well, its great they have given users the ability to use the technology, since its already there, but its not gonna make a difference. In the end, there was a reason they didn't certify it, as was stated in the article, and we know people tend to flock to any performance gain without considering if its worth the potential instability.

It's the same thing with RAM, I cannot count how many times I've read topics from people with all kinds of memory issue, and they still want to run memory sticks that are faster than the rated frequency for their motherboard, knowing it won't make any real difference.

My point is that people are too eager to forsake reliability in favor of marginal performance gains, and this might end up being the same case.

I take it neither one of you like to read the article you are posting on?

Did you both read the title, look at the article and go "To many words, will just post questions even though the answer is in the article."?

In our review of the GTX 690, we got a little clearer picture of why the GTX 690 runs a PCIe 3.0
Doug, I read the article, and no, you didn't, you just stated that as a fact, and most importantly, didn't explain then or now why Nvidia is claiming

but have seen significant variation in signal timing across different motherboards and CPUs.
and telling its customers to enable PCIe 3.0 at their own risk (and what risks are those ?), but, get this, only for their GTX 680 and GTX 670 GPUs. The GTX 690 operates at PCIe 3.0. In fact, it's the card that will benefit the most from it.

What you said in the article you link to (GTX 690 review), was this:

Why not just ship it like that? There was a reason, we are digging deeper, but aren’t yet ready to discuss the results.
So, are you ready to discuss the results now ?


Why does Nvidia not find any problems with the GTX 690 on the X79 / SB-E platform ? This smells fishy and Nvidia is not explaining something. Why do AMD GPUs work fine at PCIe 3.0 speeds on the X79 / SB-E platform ? And why do Nvidia's drivers enable PCIe 3.0 on the X79 / SB-E platform for the GTX 690 and not for the GTX 680 and GTX 670 ?

Tom's Hardware, please investigate, this story does not add up.

hello,

I have a 3sli 4sli setup . . And I tried your GEN3 exe and chagned in de BIOS settings ..
and it got worse in my case ..... from 55fps ginto 30FPS , small remark I' trying to playw it res up to 7680*1600
