SLI: Mismatched cards

Hello,

In my R4, I just installed a GTX670, which work great.  The dual GTX555 I removed where installed in another computer I have.

Now, from that old computer, I had a Geforce 8800GTX (768mb) which was an of a card few years ago.

I was thinking about mayby using that 8800 in SLI in my R4, and have it decicated for Physx. 

I know that in the past, we could not put 2 differents card in SLI.  Is it still the case?  If i can use mismatched cards, will i gain some performance with this setup for games that use Physx?

I know there's very few game that use physx, it's just that I have this card that wont do anything, so if I could put it to good use 🙂

 

Thanks!

I wouldn't. The 670 has plenty of extra power to run PhysX (when needed). Having only one card provides better cooling in an Aurora.

Re: SLI: Mismatched cards

well sli and physics card arent same .. the 670 has the power do do what it needs but it cant be sli'ed with any other card cept a 670.. and probably a dell oem only at that (see forums for issues with store brand and oem cards)

you can run it as a dedicated physics card tho which dont require sli  but again why would you want to add the heat form the 8800 in the system 😞  for minimal increase if any for the most part

Re: SLI: Mismatched cards

I agree with you guys. It's not worth the extra heat and the 670 is plenty enough without it.
