Are PCI-E 2.0 video cards compatible with the A8N SLI Deluxe? I've been told that they are backwards compatible and I have seen a few posts around saying that the cards aren't working with their Mobo's. Figured I check before I go in for an 8800 GT.

Thanks

It looks like the pci-e 2.0 cards like the 8800GT are only backwards with the pci-e 1.1 slot. The ASUS A8N sli deluxe being an nforce 4 board would have pci-e 1.0a, which according to this thread on techpowerup is not backwards compatible with pci-e 2.0.

That's a tough call. I ran an 8800GTX for a time on an A8N32-SLI Deluxe without difficulty. It runs much better on a Striker, but I had no problems on the NF4 board. That said, the architecture of the 32 offers some advantages over the Deluxe in the area of PCI-E bandwidth.

You might get an 8800 running on a Deluxe, but I think the results would be disappointing. If you're going to spring for an 8800, you might as well upgrade to a C2D rig while you're at it. The prices are so low, you almost can't talk yourself out of it.

well that blows I was really looking forward to getting one of those for christmas...Now I gotta wait till summer I suppose prices and compatability as well as AMD procs and GPU's will be out and running by then. As well as DX10.1 cards. I'm also certain that they will just be releasing DX10.27betaAniner which will be totally incompatible with any cards and hardware on the market...if the current model continues and is any indication of what is to come.

So how many boards are PCI 2.0 capable?

Only x38 boards as of now.

Though pci-e 1.1 boards will run pci 2.0 cards. See below:

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

I guess I'm with Grimm on this one too..I was hoping to squeeze a little life out of this PC before the spring/summer when quad cores start to get into full swing. Oh well, guess Ill be playing the XBox 360 for a little while.

so to clarify PCI 1.0a could possibly, with a lot of tweaking, run a 2.0 card...maybe if a pig could fly maybe.

A PCI 1.1 will run it but not at speed.

A PCI 2.0 is G2G

PCI 2.0+ is freaking awesome...

Hey Grim,
I have the same mainboard and a 8800GTS320 EVGA card worked fine on it, sorry so slow was searching the forum and saw the posting.

running a GTS is not the problem. Compared to the GT's price and power of the GTS blows. The GT is also 100$ cheaper than the GTS. The catch is that the GT will only run that well on a main board that supports PCI2.0...which a deluxe is not.

I would bet that the only time our boards will get a card with the power of a GTX with the power consumption of th GT will be the 8600 with the 65nm die shrink. If they make the same additions to the 86 that they did to the GTS die shrink I think it'll end up haveing the power of the 88GTS or 88GT...I think that made sense...took me about an hour to write that there's so many distractions...
