PCI Express 2.0

????
I'm kind of confused...is PCI-E 2 out yet or when is it REALLY supposed to be due out? When are the x38 and G35 chipsets supposed to be released?

Hmmm, okay I just did some reading up on x38 and PCI-E 2... I doubt PCI-E 2 can be fully utilized as of now, but the x38 chipset does look very promising. My opinion is if you're worried and you don't absolutely NEED the system now then wait a bit...

Yeah, it looks like the choice is completely up to you depending on if you think it's worth it or not. Does anyone know if the x38 will support the new 45nm CPUs, plus DDR2/DDR3 just like the GIGABYTE GA-P35C-DS3R?

Fr om what I've seen from the previews, companies like Abit and Gigabyte are making two different versions: one for DDR2 and one for 3 but not one compatible with both. It would be nice to have a board capable of both to easily upgrade when DDR3 becomes more commonplace.

On a side note, the nvidia 9 series is worrying me. It supposedly has 1 teraflop of computing power and I'm skeptical that any of the current PSU's on the market can handle such a beast. Something like that would generate a lot of noise, heat, and may require its own power supply.

not only intel has the PCI-E GeN2

amd/ati is working on rd790 16x16
nvidia is working on C72 and C73 along with MCP 78. im pretty sure its amd only tho
and x38 will def support pcie2

benifits of pcie2 are:

increased bandwith

doubled power output ( 75w compared to 150w )

and thats all i know up to here.. http://img.tomshardware.com/forum/ [...] icon14.gif

* not 100% sure on those new nvidia chipsets tho, but theyll come around when g90/g92 come out nov/december)

yes it supports pcie 2 because ALL bearlake chipsets support it. if you need a link

if it was me, id wait for x38.

note*

just because the chipset supports it, doesnt mean the slot will. they may need more circuitry on the board itself.. iuno


hope this answered your question.

*LOL* ssorry but some1 has already put up the link. you mustve missed it too =]

alsoo! id suggest you call them to make sure.

as nice as all that is, what does it have to do with the topic of pci-e express 2 in relation to gfx cards?

well.... ummm... bandwidth? yeah joking aside that was pretty random to state it mildly

Why?
It's backward compatible in both directions.
The only 8X / 4x issues were early poor MoBo support, which lead to the stickers proclaiming R9700/FX5800 compatible MoBos like the sticker on my old Gigabyte board. And the big MoBo makers like Gigabyte fixed the problem when it arose. So be sure to get a quality board if you're concerned.

At/near launch R600 was shown running on a PCIe 2.0 PEG slotted MoBo running with only 1 6pin power connector plugged in, and it also works in older MoBos obviously. Proving some cross-platform inter-operability.

It's really a question of providing power if you design a PCIe2.0 part and you want it to be backwards compatible it better be ready to run without the extra power and thus grab it from another source/connector, since the slots are physically the same only supplying an increase in frequency (not more pins).

Most cards will be backwards compatible leading into the middle of next generation simply because of the fact that there's not enough of an install base. After that you just have to worry when you NEED to change, not about future possibilities/probabilities.
