Saw an ad for a crappy Dell with pci express today. Price seemed steep .

$1799 cnd .

Graphics: A full new lineup of PCI Express graphics cards for true to live video and games. The new line up features both the new ATITM  RadeonTM  X800 XT and new ATITM  RadeonTM  X300 SE.

Apparantly so...

What's so good about PCI Express?

Well Kai , Glad I'm still waiting to upgrade . Don't see much choice here in canada,yet tho. Guess you need mobo that supports it, new type of memory too I'm guessing?

Memory: The New Dimension 8400 offers DDR2 Memory that enables clock speeds up to 533MGz for the ultimate PC performance.

Yep, DDR2 is new as well

AGP was, i think, reaching it's speed limits, so they needed something new. This new PCI-Express offers much faster speeds than agp.

google it for more info.

though i hear it wasnt working fully yet (as with any new technology), right now its even supposed to be slower than AGP

id wait a while before getting anything that new, let em work out the childdiseases first

Give this man a cookie.

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.
