Really???
So are you saying if you have 300 megs of data that you need the card to work on that it is going to copy to the card and back out into ram and the PCIe 1.0 bus is going to be faster then what the northbridge can handle? As I understand it PCIe 1.0 only supports 250MB/s max. Am I missing something?
PCI-e 1.1 is already gone. All new boards ship with at least one 2.0 slot. However, the 1.1 spec is still more than enough for even the most powerful cards.
PCI-e 1.1 supports 250mb/s per lane. For a PCI-e 1.1 x16 slot, that's 16 lanes.
So basically your saying that the future hardware will continue to use pci-e 1.1?!?
Sorry, nope its not going to happen. When Nehalem hits on the mac pro pci-e 1.1 will be long gone and new gpu's will at least support only 2.0 and up.
Either way, gives you another reason to upgrade. =D

If you really wanted to prove yourself right, you'd look around the Internet for the specifications on Gainestown logic boards.

Your all wrong at this rate we will all be talking about PCI-e 3.0 by the time the new Mac Pro's come out... 🙁

nawwwwwww. the Mac Pro is pretty sleek, i hope there isn't too much change about the physical appearance but maybe a small change would be interesting.

Except Gainestown is still set to begin production this month or February, meaning a WWDC 2009 release.
The 8800GT is a PCI-e 2.0 card. I keep saying that PCI-e 2.0 and 3.0 cards are 100% backwards compatible because the technology hasn't changed, just the transfer rate. Likewise, PCI-e 1.1 cards are compatible with 2.0 and eventually 3.0.
I wouldn't be that surprised if the tylersburg used all PCI-e 2.0 slots, but it's not really necessary yet, or for the next year or two if graphics cards keep improving at the current rate.
I don't think you understand what I'm saying, lol. 🙁
My point is Nehalem or for a year from now, there will be no point in the newer hardware/motherboards to support pci-e 1.1 when newer cards will support at least 2.0 and get ready for 3.0.
Just because pci-e 1.1 is compatible with the 2.0 cards doesnt mean that it wont get crappier transfer rates, sure it will work but you wont get the benefits to go with the new cpu architecture.
I dont think you know what I'm saying.
They automatically support it, they're just different versions of the same spec.
As I've said before in this topic, even the GTX 280 and 4870X2 don't get close to saturating the 1.1 bus, so the difference in transfer rate makes no difference.

But will it still sustain only saturating only close to the 1.1 bus with nehalem? No one knows that right now what gainestown will bring. But I got my money on saturating that 2.0 bus fully or close to it as you would say.
It's just the the output of the graphics card. Core i7 and the X58 don't change that.
As I said before the 1.1 bus is nowhere near saturation, and the 2.0 bus is double the 1.1 bus.

New motherboards of the gainestown could change that very easily as to the inferior architecture right now.
For now we dont know what they are capable of as it is not released yet but you would really have to think this time around the specs that the cards have should be at least utilized with totally new architecture.
This is simply not true since a person can buy a version of Roxio Toat 9 or 10 and burn Bluray movies for free once you bought the software.

Also true, but you can't burn video with HDCP on the disk in either Toast, OS X, iDVD, or Final Cut Studio 2.
That's the bag of hurt: HDCP.
The board isn't going to magically make the graphics card pump out more data.
I believe he's talking about a license for the studio, similar to the one time $2500 fee that Intel charges for USB. Obviously end users aren't effected.

But the newer gpu cards that are out when gainestown is available will be able to pump out more data and not to mention the snow leopard! 😎

Snow Leopard slowly rearranges your hardware's molecules to upgrade itself to smaller manufacturing processes.
Once you install Snow Leopard on a Nehalem Mac Pro, it will upgrade itself and become a Sandy Bridge Mac Pro within two years, completely skipping Westmere!
Is there an echo in here?! Seriously?! 😀
It won't matter what the Xeon 5500 series parts, the X58 parts, or any specific board can do. It's in the PCIe specs, and is hardwired into the PCIe controller bus.
Fortunately, the newer versions are/will be backward compatible. So if you manage to get a board that's strictly PCIe 2.0, your PCIe 1.1 cards will still work. 🙂
