When will the pci express motherboards be out? In June or July is this correct?

If I buy a pci express MB will the Radeon 9700 pro work on that MB?

I dunno if I should wait for the new pci express MBs. Should I wait or not.

I think graphic cards are still not even using full AGPx8.

PCI-exp for graphics maybe by sept. Your 9700 pro wont fit. 16X PCI-exp is about 3x faster than graphics can use downstream. If you are looking for some high-end video-in, it might be worth it. As for PCI-exp 1X and 2X , next year. Same story here. No real use, maybe later.

I have a feeling mobo makers will make boards with both AGP and PCI Express for a while.

i've heard that for whatever reason pci ex and AGP dont play nice with one another. SiS was developing something...but on most mainstream boards i dont think you will find AGP even in the first implimentations of ex.

If it isn't a P6 then it isn't a processor

as far as I know, no. totally different bus design so not a chance.

However, I think I read somewhere that early PCI-E boards will have a normal PCI slot or two in addition to the others.

My understanding is that it will be one or the other only. I think (not sure) that bothe interfaces cant be supported on one chipset.
If that's the case I would assume that some of the newer mobos will come in two different flavors, either AGP or PCI Express. Otherwise if you want to upgrade your mobo but not your vid card you will be screwed especially if you just plunked down $400 on a 9800XT.

If I buy a nForce3 Pro 250 motherboard will it still be top of the line when the first pci express MBs come out?

And when will the performance of a pci express graphic card be used in a pc games?

Two really good questions. One can only speculate. History tells us that your nForce3 Pro 250 mobo will not be top of the line when PCI Express comes out but it'll probably be close. As far as pc games utilizing PCI Express, I'm sure the games coming out now would benefit. I have a Radeon 9700 Pro that I now have to overclock to get decent frame rates at 800X600 in Farcry.

What do you mean by « high-end video-in »?

Witch motherboard are you talking about?

And what does the nforce 3 chip do on the MB? I don't think my MB I have now has a chip.

What's the rest of your system like? I am using a 9700 Pro and I play Farcry quite happily at 1024x768. Are you talking about exceptionally high frame rates, or all settings maxed?

I think nvidia was working on an AGP to PCI-Express adaptator in order to satisfy customers who don't want to spend 500$ for a new video card.

I think that was simply a chip/circuit which allows them to dramatically cut down the amount of differences between a PCI-E and AGP version of the same card - so they don't have to re-design too much.

It's never going to be released in the form of an adapter, AFAIK.

More to the point - I don't see how you could fit any kind of adapter between one slot and another and remain within the ATX spec (i.e. make sure the back of the card lines up correctly with a slot on the back of the case)

What Nvidia was developing was a PCI-express to AGP Bridge(or other way around, can't rmember how you designate it), so they could use an AGP GPU on a PCI Express board. ATI is, or was hitting on this, claiming they will have the only actual Native PCI Express solution(to start at least). This has been my understanding anyways.

So the "adapter" wasn't really an adapter to let you use any card, but a bridge for use on the card itself, so makers could use AGP GPUs when they make PCI Express video cards.

I knew it was something along those lines - i.e. not anything of any use to us. We'll still need to buy a new gfx card if we get a PCI-E mobo.

Can someone tell me what the nforce 3 chip does? Does it boost the performance of the graphic and sound card?

If it does why would I need pci express? I think the performance of a pci express and nforce 3 250 motherboard would be the same. Unless the pci express MB's will come with a nforce 3 chip or better. Am I wrong?

I don't think there's a reason to wait for a pci expres MB. Maybe in a few years I will buy one.

Can someone clearify this?

All motherboards have silicon that controls the interface between the cpu and devices , like usb, hard drives video etc. In most cases this requires 2 chips, and is called a chipset. In the Nforce3 case, this is handled by a single chip (North Bridge) I have taken to calling it the Nforce chip.
Pci express for graphics is slated to start at 16X. This is 4x faster than most current agp cards. This doesn't mean that graphics cards will become 4X faster, but that the interface will be ready when they do. This will probably take from 3 to 6 years.

I'm sorry for being vague. I indeed like to run my games with all the settings maxed. I can run Farcry at 1024x768 but occasionally frame rates drop below the 30fps and it begins to get choppy. My system is as follows:

P4 2.8 @ 3.36GHz
MSI Neo-LSR
1GB Kingston HyperX PC4000
ATI Radeon 9700 355/324
Other really cool stuff

I think nvidia was working on an AGP to PCI-Express adaptator in order to satisfy customers who don't want to spend 500$ for a new video card.
Knowing Nvidia it probably won't work with ATI cards! :lol:

Can someone please give me a link to a website where I can find out what kind of cpu will fit in the first pci express MBs?

And I also need to know what kind of chips the first pci express mbs will have.

It'll be an LGA775 P4E. Chipset choices will be intel Grantsdale or Alderwood.

*Dual PIII-800 @900 i440BX and Tualeron 1.2 @1.7 i815*

Are those for the first pci express MB from Asus JCLW?

The first Asus motherboard with PCI express will be P4S800DP-E deluxe

Does anyone know if a AMD Athlon 64 FX-51 socket 940 and this kind of memory will fit in that motherboard?
