confused about pci-e

[SilverJag]

Hey,

Ok so does pci-e come implemented on the video card or mobo? Lets say i get an Asus a7n8x-e deluxe, will i still be able to use pci-e? In other words, is pci-e an addon card or it comes assembled with motherboard? since i plan on buy an x800 pro, i should wait untill it comes out with pci-e? thanks

PCI-E is a type of bus (like ISA, PCI, PCI-X, and AGP). To use it, you need both a PCI-E motherboard, and a PCI-E card.

The A7N8X-E does not support PCI-E - only PCI and AGP - so you'd need an AGP X800 to go with it.

Do you think I should wait untill PCI-E comes out or should I just buy the X800 Pro on an ASUS A7N8X-E Deluxe and a 2500-M @2.46? Will there be a bottle neck due to the fact that the CPU will be rather slow and the video card will be fast?

That's what we are all waiting for. We have all seen the theoretical specs behind PXI-Express and what it will give us in a performance boost. Until it ships and is tested side-by-side with older systems nobody knows. Usually theory and reality are very different.

I'm almost 100% sure that u won't see any difference between AGP and PCE-E with current cards. Maybe the cards that will come out 2 years later will be so fast that the AGP bus would be the limiting factor, but now it's pretty fast enough, even for the x800 and 6800 :D

I posted this in another thread but I'll post it again here:

There is a lot more to PCI-E then just bandwidth. For example: AGP provides a fast data path in one direction only, but PCI-E provides for extremely fast data transfers in both directions with no "switch around time" to switch directions. This allows the GPU to used to quickly perform calculations that the CPU would otherwise have to do (calculating grenade blast radiuses was an example one game developer gave). PCI-E also allows multiple graphics cards to be used. PCI-E also increases the power available to graphics cards (PCI-E X800pros will not have a molex or BTX graphics card connector).

Of course there won't be any games out that take advantage of PCI-E for a long time (until the majority of the user base has PCI-E cards), but we may soon see some nifty demos that only run on PCI-E cards. Or we may soon be able to fold or run SuperPI on our GPUs.

I agree. Right now most video cards don't even take full advantage of the 8x agp slot. Most people don't even notice a difference between running at 4x and 8x agp.

I'll agree with that too, i used to run a FX5600 on 4x then 8x on diff mobos.. no real improvement.

lol doesnt that make you 90% sure, but I agree, untill they make cards specifically for PCI-E than there shouldn't be a performance boost. You will have to wait for the generation after this next generation. umm ok the generation after 6800 and x800. :beer:
