Using a 9800GT as PhysX with a GTX 560 Ti

[HoLoDreaM]

I just bought a PNY GTX 560 Ti using some gift cards I got for xmas! I'm currently running dual 9800GTs in SLI so I figured I'd use one as a PhysX card along with my new 560. I'm using an Antec Earthwatts 650w PSU and I'm wondering if that would be enough to power the 2 cards? Would there be any real benefit with that 9800 at all? And do you need to hook up an SLI bridge for the "PhysX" card to work? System specs are currently in my sig. I also just won a Kingston SSD in the Christmas Contest here, so add that to the list.

For physx you won't be needing your SLI bridge. But I must tell you one thing, that using 9800 as dedicated physx card won't help you too much if not at all.

A 9800 will be a great physx card, you don't need a very powerful card to run physx, you basically just need a card.

This has nothing to do with the question in topic, however, can i use a 7950gt as a Physx card ?

I don't see why not, and if it doesn't work, no big deal.

The faster your main cards, having a slow dedicated PhysX card will bottleneck your performance.

+1 that needs to be noted as well.

No you can not. You need a card that's 8000 series or greater with 32 or more cores and more than 256MB of VRAM.

I recently bought an EVGA GTX560ti DS and would like to use my old 9800GT (Also by EVGA) as a dedicated PhysX card, do you think I will be bottle-necked? I mean, that 9800gt use to be a beast of a card and I am still able to run BF3 with it at 1600x900 low at a steady 25-30 FPS.

because you need an 8000 series card or newer or simply the AGEIA physX chip which isn't on the market anymore.

you could use to 7950 gt for phyx as it does not support physx
