What, if Any, PCI-E card for 8x Slot?
Anyone know of a Nvidia card that will work well in an 8X PCI-e slot? I have a Quad Core machine sitting around with 8x slots and wanted to us it with my Vision setup. (Using a laptop right now, and it wors, but I would like more power than my 9600).

If one works, which one has the most power?

Thanks

maximum i believe is a 250GTS which is a effective rebadged 9800GTX.

*EDIT* maybe not actually! I dimly recall a friend upgrading to a 250 and having to get a new mobo to go with it. :(
Might not be a bad idea to go that path + a 260 in there (if you can source them these days..)

- That would work for me, is there any documentation that confirms it working in an 8x slot?

All card will work, if PCI-E 2.0 you will get -2% perf if PCI-E 1.0 you will get -30% perf

That isn't strictly true - it certainly wasn't on the shop built pc (black screen on start up with the card, fine with psu in different mobo) and it certainly aint for some Dells as they get a plastic riser in there to stop you plugging it in. While it shouldn't be the case just Google around you'll see it crop up.

You cannot plug an x16 graphics card into an x8 slot. You can however, if you wish, plug an x8 card PCIe card into an x16 slot. A p-lane PCIe card will work at some speed in an n-lane PCIe slot, where n > p. This is not true if n < p.[/quote]

Yeah, I've read stuff like that - which is why I decided to post a question. The slot doesnt have the plastic piece like some Dells, in fact its a repurposed Intel S5000PAL board (Dual CPU/Quad Core).

I have a riser and it can take an 8x card, My thought was a 16x Newer card - even in an 8x slot, would outperform my 9600M GT in my laptop.

Best bet - buy it from somewhere local so that you can try it & easily take it back if it fails :)

x2. It will work and the performance loss will be minimal, if it's PCI-E 2.0
