Pci Express

The technology is sorted, but the only cards currently available are graphics cards (AFAIK). any testing done has tried to utilise the GPU's features to the maximum, and has so far shown that the speed is more or less the same as AGP. But since the AGP port wasn't the bottleneck in that sort of test that's hardly surprising.

By definition this means that the GPU is the bottleneck so it hasn't tested bus performance.

Secondly, AGP is simply a branch from the PCI bus, albeit directly from the Northbridge. This means that when the AGP bus is in use, the rest of the PCI bus is blocked (and vice-versa), even though the Northbridge may be otherwise relatively free of traffic. With PCI-x each device has its own bus, so although individual speeds may not be much higher (at the moment) there is no bus conflict so overall performance potential is not limited in the same way.

That said, I think I'd wait for socket 939 with PCI-x. Real futureproof investment.

In lamens terms:

The graphics cards they tested with aren't fast enough to test out the PCIexpress slot\port properly. Even AGP was fast enough for these graphics cards, so you won't see a difference form agp to pci express...yet.

Well, don&#39;t know if this counts as anything, but I just bought a PCI Local Bus video card, it&#39;s a GeForce4 MX 4000, for only &#036;70. Only reason is because, well, my mobo is kinda old, (Pentium III @ 1GHz), so, no AGP slots for me. This PCI card works fine for me, untill I can get enough money for a gaming comp.

It&#39;s not necessarily that it is old, but that it is a cheap motherboard..

my 450mhz p3&#39;s motherboard (an asus something) has an agp slot...

Well, I hate to say this, but my parents bought this comp off of our local ISP (big ****ing mistake) I&#39;ve beefed it up majorly since then, but still, it&#39;s junk.

Your ISP sells computers.

Indeed.

Note the use of the new "Canadian Abridged Alphabet" which eliminates the troublesome "Y" in favor of the long A.

Eh?

"Lamens" is the modern equivalent of "layman&#39;s".

Sheesh, get with it, VB.

Is that sort of the way some gsm-providers and similar do it, sign up for a subscription- get the hardware(like getting cell-phone, if it&#39;s for, say, the gsm net, or &#39;puter, in this case), cheap?

&#39;cos I&#39;ve never seen anyone do that with &#39;puters before.
