Finding information on the compatability of PCI-E 2.0 cards with older motherboards seems to be elusive at best.I would like to put some self confirmed info on this subject out there.

I purchased an XFX 8800GT which is PCI-E 2.0,which i have installed on a Bio-Star T-force
939 board(pci-e version 1.0a compliant)and works great.

I also intstalled the 8800GT on a Abit AT-8 board(pci-e version1.0a),and it works fine in this mobo also,obviously not in crossfire though.I was told by a tech at AMD that the X3200 chipset on the AT-8 would support 2 PCI-E 2.0 cards in cross-fire.

As far as I know all P35 chipsets got 1.1, 680i got it too

nForce4 PCIe 1.0a
MCP67 PCIe 1.1
MCP61 1.0a
RD580 PCIe 1.0a
RS600 PCIe 1.0a
RS690 PCIe 1.0a
P35/P31/Q33/Q35/G35/G31 1.1
P965 and X975 1.0a

yet another example:

Your motherboard has got the 1.1 pcie

FUCK!!!! my GF got me an 8800GT for x-mas that i cant have yet and now it isnt compatable with me mobo?!

It's perfectly compatible. PCIe 2.0 is reverse compatible with 1

but its nf4 it says 1.0a which is incompatable to my knowledge least thats what everyone said on like the first 2 pages

Check the post above your first one. It should be fine.

lol. That's the breaks in this type of relationship. I usually have to make unsavory promises to get goodies. lol

all pcie 2.0 cards will work fine on any pci-e motherboards.
any pcie 1.x cards will work fine on any pci-e 2.0 motherboard

the main benefit of pci-e 2.0 is that the transfer bandwidth has been increased. however, many gpu board designs are not even designed to handle transfer speeds of 4 GB/s, most give you 1-2 GB/s in reality.

does it make any difference in game FPS ? I dont think so. For a quick test set your port speed to PCI-E 8x vs. x16. The difference you will now see is the _maximum_ incerase you will be able to get going from PCI-E 1.0 x16 -> PCI-E 2.0 x16 which is just like x32 in terms of bandwidth
