Everyone knows about the new nvidia cards coming out in november i think :-S???

And apperently going to be using a PCI-Express 2.0 slot? meaning we all going to need new motherboards :-( ???

Matt.
 
Not officially confirmed yet, and as Jokester said we don't need new motherboards. :)

Be a long, long time before were all needing to move to PCI-E 2, look at how long AGP was around till PCI-E came along, i didn't move to PCI-E till November 05, not even 2x years ago yet, was on AGP for absolute eons.

Every 6 months after nvidia. :p :p ;)

Good one. :D

Supposedly the R700 is the start, their GX2 card is around January (no clue what they are thinking there), then 6 months later R700 will appear, then its a new one every 6 months after they rekon. :p

PCI-E 2 will be backwards compatible with current motherboards.

What does this mean exactly? If its backwards compatible then why do they bother make PCI-E 2 at all? And will PCI-E 2 boards be avalible? if so what advantages would they have?

It seems like having an xbox and saying dont buy an xbox 360 because all 360 games run on xbox.
 
That GFX cards based on PCIe 2 will still fit and work on PCIe 1 mobos - if thats too difficult to understand then compare it to AGP 1x,2x,4x,8x...

PCIe 2 boards will become available and will basically just provide aome more bandwidth across the bus - much like the numerous AGP revisions...

IIRC its more about quality of the connection than the bandwidth thats changing...

You didn't read what i said. I asked whats the advantage or even, whats the point of PCI-E 2 if it works the same in PCI-E. You say they provide more bandwidth. So does this mean the card will function better? Or what? I dont want to just buy a new motherboard. Then get a card which isn't running its full in the motherboard i just bought.
 
PCIe 2 is basically a better quality standard to ensure better communication across the bus (reduction in power jitter etc.). It also introduces the PCI 32x lane...

Its identical a change as AGP 4x going to AGP 8x...

If you have a PCIe 1 board unless the card requires a PCIe 32x lane then you will be pretty safe since they will still use the same form factor...

If you have a PCIe 2 mobo then you could still use your old PCIe 1 GFX card without any issues...

I only went to PCIe in december last year with my 8800GTX, Was on AGP 4 & 8 for ages :).

I've heard that the new PCIe 2 cards won't run to their fullest potential on PCIe 1.

Mate you didnt read what he said.

Stop confusing yourself and just listen.

PCIE2 will probably offer no performance advantage over PCIE, just as PCIE offered no performance advantage over AGP for a long long time.

Though obviously if buying a new motherboard in a few months, it would make sense to get PCIE2 just for futureproofing.
 
Thxs Dave2150 - thought I was speaking another language back there :p

Intel support PCIe 2 with X38 chipsets, unsure about nVidia or the other chipset manus...

EDIT:
Wiki said:
Intel's first PCIe 2.0 capable chipset will be the X38 and will be released in Q3 2007. AMD starts supporting PCIe 2.0 from its RD700 chipset series. NVIDIA has revealed that the MCP72 will be their first PCIe 2.0 equipped chipset.

He's right, but we're talking about a difference of only a percent or two. It's like the difference between running x16 and x8 at the moment. Basically not something to get worried about at the moment. It won't be a few years before there will be a significant difference between PCI-E 1 and PCI-E 2 as current GPUs don't max out current PCI-E slots.

So basically running an AGP 8x card in an AGP 4x slot?

I remember when I first went to PCIe - ran a X850XT PE in a x16 slot running at 2x speed (was on lower slot in non-SLI mode) on a DFI SLI-DR and I lost no credible performance (3dm05 was literally a few points different)...
