DIRECT X 10- WHEN IS IT COMING OUT
IS PCI EXPRESS FASTER THAN AN AGP SLOT

DX10 is coming out when Windows Vista comes out.

PCI Express is capable of double the bandwidth of an AGP sot, but current cards cannot take advantage of the extra available bandwidth.

yes exactly but one problem, i highly doubt they will make an AGP Dx10 card

Not just highly doubt...they won't.

Seeing as they didn't make AGP versions of the best of the current generation of cards.

They did make AGP versions of current cards. AFAIK there's an AGP X1950 pro and a 7800 something. But these will be the last of the AGP cards because dx10 cards are designed to do more general purpose computing. This requires lots of bidirectional bandwidth, something the 1.0 spec of PCIe mearly adequate for. Since a 16x PCIe slot offers 8GB/s total bandwidth (4GB/s up/down), 8x AGP's 2.1GB/s simply won't cut it.

I know, but there are no AGP versions of say, 1900XT(X) or 7900GT(X).

I'm only using common sense/logic here, no real bi-directional this that and the other to back it up.

Let's say that while it's not impossible (Nvidia's translator chip is generic enough to work with newer chips) it is highly improbable that we'll see DX10 cards on AGP slots.

About bidirectional throughput, for gaming cards it is not really that relevant - as games don't need that much GPU-to-RAM bandwidth. Other uses are still marginal enough to make it a non-issue.

Was waiting for that, nice one! lol.
