GTX580 + GT220 Dedicated PhysX
Hi, new to the forums here.

I have a GTX580, and I'm wondering if adding my old GT220 as a dedicated PhysX card will make any improvement at all?

In the Nvidia control panel, under the PhysX tab, when I set the drop down box to 'auto-select' it selects my 580, but I was thinking it might just be doing that because obviously that's the more powerful GPU of the two.

I don't really have anything other than Batman: AC to test the differences between using the 220 or not, but that's a bugged mess, so I can't use that as a fair test.

Thanks in advance for any help you guys can give me.

The GT220 will likely cause a performance loss over the GTX580 alone.

It's too weak of a card.
The GT220 will cause a serious performance hit in games supporting PhysX, as Raptor has said. Even a GTX 280 would be borderline. A GTX 560Ti would be the best PhysX card to complement a 580, but a GTX 460\470\480 would also provide benefits.

My advice would be to just forget about adding a PhysX card. The only time it makes sense is when you have an adequate GPU laying around that you can use as a PPU (the GT220 is not adequate in this situation). Buying a GPU solely for PhysX is a huge waste, unless of course you can get the card for pennies.

Cheers for the quick response both of you.

I didn't think the GT220 would really stand up to the GTX580, but I thought it a waste to just box it away, but from what you both say, I'll not bother with the dedicated card.
