Currently got asus p8z68 v gen3 mobo with 2500k, so to get pcie3 i just pop in an ivy, is it worth it? Upgrading gfx shortly to 670 gtx, would there be any gains in getting an ivy, sure i have read somewhere that the gains are only a few fps, is this hardware or driver related currently?
 
Current top end GPUs aren't bandwidth constrained so moving to PCIE 3.0 isn't going to give you much if any performance improvement.
 
That techpowerup test that folks like to link to is only valid for single cards.

The results would have been quie different if they had done a proper job and used some 680's and 7970's in SLI/Crossfire.

PCI-E3.0 8X/8X is equivalent to PCI-E2.0 16X/16X

HardOCP and Tomshardware have done SLi/Crossfire tests at 16X/16X, 8X/8X etc 2.0, its only 4X that makes a noticeable difference.
 
On Z79 boards, using 680 SLI or 7970 CF, on multi monitor setups, PCI-E £ is VERY important.


Otherwise, it's mostly useless.

I have to disagree.
Try this
Take a pair of 680's and stick them in a z68 gen 3 or Z77
Run Heaven,

Swap out the SB with an IVY, clock speed not important.
Re run Heaven.

You would be very surprised by the difference.

I assume you've done this or seen it done.

Please post the results or a link to them.
 
So does this mean with the current generation of cards 6** & 79** that pcie 2.0 is more than capable of supplying the bandwidth(single card useage), do you think big kepler will change this??? Or have some of us been premature in futureproofing our systems, what i mean is will the likes of the mobo i bought be obselete before pcie3.0 has matured/gfx cards can use the extra bandwidth which the new standard gives.
 
I only ever use a single gfx card(1920x1080 res), which is why i need to replace my 280, struggles with bf3 abit medium only :( but would like to see some results on pcie3, single and sli if anyone has any.
 
I expect someone will post up some comparisons i wil not.
The deletion of screenies in the Heaven thread was the straw that broke the camels back for me.

I also have little patience for the misinformed and arrogant.

What was the real reason? You sound very bitter.
 
Image size may have played a major part in the deletion of images.

Posting images.
You may post images providing they are hosted by a well known image hosting website, such as imageshack, photobucket etc.. Directly linking to images on other sites that are not expressly for that purpose (known as Hotlinking) is not permitted. Hotlinked images will be removed with an infraction notice issued. Repeat offenders will be suspended. The sharing of images from your own personal web-space is acceptable providing you are the owner and give permission to do so. However, the OCUK moderation team reserve the right to replace or remove any image that is suspicious of being hotlinked or unknowingly hosted by a members personal web-space, as it is not possible to identify those where permission has been granted or otherwise. Such decisions will not be overturned. To avoid complication, we strongly advise that all images are hosted by a image host as mentioned above, which can be easily identified as so. Images containing nudity, adult or offensive material, including swearing is prohibited. Please check your images before posting. No watermarks or URLs for sites containing content that wouldn't normally be allowed such as competitors, adult sites etc. Any images of such nature will be removed and your account immediately suspended or banned. Unless otherwise agreed by the moderation team, images must no wider than 1024 pixels wide.
