Would a 260 c216 physX card slow down a 480 sli setup?

Would a 260 c216 physX card slow down a 480 sli setup? Just curious because I'm seriously debating picking up another 480 from EVGA b-stock since they're so cheap ($220) but I sort of also want to keep this 260 since it has an EVGA lifetime warranty and if it dies down the road I think they'll toss me an upgrade (lol) ... plus my new mobo has 3 pcie2 slots anyway

Yes there is a chance that the physical card could slow down the sli setup

not that much, but i think its not the best to do. 2 x 480 is more than enough

No.

In my experience &benchies(via OCN search option), a 260 would not slow down a single 580 setup or a 460SLI, a dedicated 260 increased frames(20+) on mafia 2/batman AA. However, anything less than the noted 260 would SLOW down PhysX enabled games.

Cool. Was that a single 580 or sli?

Why bother? I've played batman/mafia II/alice with physx set to high and with nvpanel setting physx to run on 2nd card the performance is perfect and 60 fps even with a ton of effects.

you don't even need to have the other 480 for Physx processing. A single 480 can handle physx fine on high setting for Batman, Mafia., Might drop to mid/high 40's once in a while or when there's a lot of stuff going on, but it's generally relatively smooth.

My 2-part answer:-

1) GTX480 SLI + GTX260 (Physx)
This setup almost certainly will give better Physx performance than without the Physx card.

Brettjv has done a very similar study with GTX470 SLI + 8800GT. We know that GTX470 SLI is certainly in the same performance category as a pair of GTX480s while the 8800GT is (much) weaker than a GTX260.

His result shows that a noticeable benefit with the 8800GT. Note the graph in post #2 here:
http://www.overclock.net/nvidia/1024...ally-help.html

So, I think this part is quite certain. The only 'worry' is the heat management.

2) GTX480 SLI
If you decide to get another GTX480 to do SLI and ditch the GTX260, remember to specify the 2nd GTX480 to be the Physx card.

Brettjv (yes, it is him again )has also done a study on using 1st card vs 2nd card (GTX 480) as Physx card. He found that using the 2nd card would bring better performance.

Note the graphs in his thread here:
