i have an 8400gs 256 MB card,
and want to upgrade

I'm planning to buy a gts 250, but my monitor doesn't support DVI

Can i sli the cards?

if not, can i set up the rig so that the GTS250 does the processing and the 8400gs does the displaying?

No you can't SLI them,the cards have to be the same model.And no its not possible to use both cards.

Yes that's possible. You can use one card for PhysX and the other one as the primary card but you can't SLI them.

Can the 8400GS be used as a PhysX card? The list on the Nvidia site starts with the 8600GT.

But as the 178.xx drivers won't recognise some of the newer cards or be optimised for newer games that would seem a bit pointless to me.

Yes,that's the downside of it.
Even if newer drivers supported it,it was still pointless because it doesn't offer a great performance for PhysX processing.But still,its better than nothing :D

It's strange,Nvidia has posted that only the Geforce 8 cards with a minimum of 32 cuda cores will work but with in the new driver's release notes(260.99) for 8400GS,it says that it contains PhysX software
http://www.nvidia.com/object/win7-winvista-64bit-260.99...
"Includes PhysX System Software to version 9.10.0514."

Good for you :)

The driver is a "one size fits all" type of thing, even the 263.09 driver that's for the GTX580 only can be made to work on other cards if the .inf file is modded. But you're right about the 8400GS not being on the list for PhysX cards as that list starts with the 8600GT.

i'd still upgrade the 8400GS to at least a GT240 or GT430 even if you just want to run PhysX on lower levels
but for gaming performance you're gonna need a GTX260 or greater for that..


Im not buying a new card , i had the 8400 lying around

Besides not many games support physx ,
although my fps in gta iv went up from 39 to 49

I have used a 8400gs as a phsyx card and not matter how high one clocks them they are far to weak and have once used a 8600gt as well and it is barely any better. Pushing the shader on it to 1.8ghz barely helped.

i personally thought the 8600GT was the lowest you could go for PhysX..


In a way one really doesn't want to go below any thing on par with a 9600/9800gt for physx as it can be a hog in some games but not so much that one needs any thing more than a GTS250. For those who like my self who have a GTX460 or better just nuke the shader and the added boost will make up for any lag that physx makes in most enabled games.

So possible but pointless is how I read that, correct?

Yep pretty much, any thing less than a G92 or G94 isn't going to hold up to the load.

I may get a chance to test that out for myself soon when the GTX560's become available as I intend to pick up a couple of them to either run in SLi or singly depending on how the E8400 copes. So thank you for that little insight.
