Too bad Asus didn't implement it into their P5K series.

P35 supports PCI-Express 2.0

I don't think mainstream users will care too much about it; the only people who will care will be people using SLI/Crossfire which will be looking at X38 boards anyway.
At least I'm very happy about the fact that P35 motherboards support PCI Express 2.0, since I really don't want to wait for X38 to be released and after that wait some more for the prices to drop. The reason why I want to get the new version of PCI-E is because I upgrade my computer pretty rarely, so now when my P35 board is stuffed with all these new technologies it will last a little bit longer (e.g. when they start to release cards designed for PCI-E 2.0, I don't have to buy a new mobo... again.)
Just implement the damn PCI-E 2.0 already to P5KC, ASUS! 😉

a lot of features the P35 northbridge has been overlooked by mobo manufacturers
the P35 has native Gigabit ethernet but everyone uses marvell external controllers
It has pci-e 2.0 but no one uses it
I heard it can split pcie lanes into dual 8x but again everyone has decided to use 16x 4x(not sure about this one)
I hope DFI does it right
according to the inquirer,DFI already have their P35's hitting 600+ FSB using core 2 duo E6600's

965 could do that do but no mfr chose to do it.
Asus are doing a couple of top-end P35 boards with dual x8 - it takes additional hardware so it's a dearer option for a mobo mfr to implement.
In the lab - other (abit, Asus etc.) retail P35 mobos have already hit 600fsb for users.
P35 has an "integrated Gigabit LAN Controller", but it's not "native" in the sense of the NVIDIA chipsets. It still need a Network Interface Controller, not just a PHY transceiver. Realtek RTL8111B is more used than Marvell 88E8056.
"it is pretty challenging to implement this technology as circuitry needs to be re-routed and additional components have to be added to ensure signal integrity."

Just out of curiosity, what exactly is the problem with PCIe 1.1???

Well that's why the article says, and I quote, "Today, another hidden gem was uncovered, ...". Which sums it all up that this feature was previously unknown to most people and was never publicly announced.
Nothing so far. PCIe 2.0 is improvement for it, which basically increase the power draw limit to 300 watt (I think the current 1.1 spec is limited to 75 Watt) and also double max bandwitdh (I think it doubles ... correct me if I'm wrong on this).

I don't see any real-world benefit right now from PCI-E 2.0. No card is currently bottlenecked, and video card are about the only thing that uses PCI-E heavily. Most other peripherals that I've seen are still PCI and not PCI-E. At least that has been my impression thus far.
It seems that these new features are more for marketing sake than anything else. (Ala ATA-133, etc.)

Yes, from 2.5 Gbit/s to 5 Gbit/s. A x32 connector can transfer data at up to 16 GB/s in each direction.
At least I am not going to buy a new motherboard before PCI-E 2.0 has been implemented because sooner or later there will be graphics cards supporting the new standard - after that part of the performance (and money) will always go to waste when buying a new GPU. Just like AGP 4x vs. AGP 8x.
I upgrade my computer so seldom that I want state-of-the-art when I buy something so I can go with it as long as possible.

Yeah, but PCI-E 1.0 x16 is twice as fast as AGP 8x, and yet, even modern cards aren't being bottlenecked by the AGP 8x interface. So unless video cards become 4x more bandwidth-dependent, immediately - then there is no real technical reason for PCI-E 2.0 at this point in time.
Just like there is no real technical reason for ATA-133 over ATA-100, or even SATA-150, save for asthetic reasons (smaller cables) for SATA.
AGP 8x was never necessary during it's useful lifetime. Only current top-end cards are even showing minimal improvements from more than 8x PCI-E bandwith. They aren't going to saturate a full x16 slot in the timeframe that any board you buy now will be useful. You aren't going to be dropping a $600 card into a three year old system I hope. You'll have a bigger bottleneck from trying to run such a card with an obselete processor and RAM than you you would get from having an interface that is 5% slower than the cards ideal external bandwidth needs.

Sorry to resurrect an old topic.
Does anyone know what is the current situation of P35 motherboards and PCI Express 2.0? Was this news nothing more than a scam, or what's the deal with the PCI Express 2.0 support on P35 boards? I don't see anything about PCI-Express 2.0 support in, for example Gigabyte GA-P35-DS3R specs in Gigabyte homepage.

It was a false rumor started by someone who misinterpreted the P35 chipset block diagram which shows 8GB/s bandwidth for PCI Express x16 and 500MB/s for PCI Express x1, apparently believing the figures cited were unidirectional (each way) rather than bidirectional (combined).
Had this person thought to cross-check this with P965 block diagram or even the much older 945P chipset, there would have been no confusion.
Ain't the internet great?

Thanks for clarifying this up for me.
