Question regarding real world value of dedicated PhysX card
 
Would it be worth it at all to put a GTX260 alongside a GTX580 for a dedicated PhysX card?

From what I'm seeing it seems to slow it down.

Any other real world experience or decent threads / research regarding this?

i wouldn't. there are reports that it can make a difference, but not with the 580,god forbid.

if you had a 5 or 6 series ati card? sure, better some than nothing.

hmmm... I haven't used a GTX 260 myself, but it might be powerful enough to help. The thing about having a dedicated physX card is that it lets you increase other settings in games that use physX.

Still, the small number of titles that use PhysX, it's only worth going dedicated physX if the price is right for a performing card. I can tell you that anything less than a 260 will hold back your 580, but I can't tell you if the 260 will or not... but I'd guess not. Still, I wouldn't ever pay over $70 for a PhysX card. There just aren't that many games to take advantage.

So from what I can see is that the GTX260 *should* give me about 10% FPS increase. Maybe.

Sound reasonable?

factor in 'sand going where it shouldnt' err...drivers and such?

not worth it.

You'll only see a slight improvement in Physx enabled games, if your playing at less than 1920 x 1200 Res the single 580 is ample. Also by tossing in the 260 means less "air" for your 580.

Yeah, best case scenario seems to be about 5fps, or 10%
