2 way sli gtx 680 with dedicated physx card
Hey all I'm new here and would really appreciate some advice
I'm about to install 2 gigabyte gtx 680 oc's in a water cooled sli configuration.
I've got a GA-X58A-UD9 mobo. This should be heaps I power for fps.
My question is how would I install a gtx 470 for physx on this mobo.

Should it be 1st, 4th slot for the sli cards and then 6th for physx?
Or
Should it be 1st, 3rd slot for the sli cards and then 5th for Physx?

Dose a dedicated physx card have to be connected to the sli cards via a sli bridge?

If any one has seen this done on a UD9 I would really like to hear from them/ask a few questions

Cheers

Your manual will tell you where to put the two cards for SLI. It doesn't matter which slot you put the PhysX card in, but you'll want to space it out as far as possible for better heat dissipation. You do not use the SLI bridge for the PhysX card.

After having said that, you don't need and won't notice a difference with a GTX 470 as a dedicated PhysX card and you'll just be adding extra heat to your case.

Just make sure you put the cards in x16 slots, not x8. If you use a x8 slot, one of the x16 slots will back down to x8, too. If you pick the wrong two, you could end up with both cards running at x8. While not a total disaster, it would be a shame when you have so many slots to choose from!

Your second suggestion is the one to go for - Slots 1 and 3 for the 680s and slot 5 for the 470, if you use it. That way, they all end up in x16 slots, with a gap of one card width between each.
