Help with a dedicated physx card

[TheResidentEvil]

I have a

Q9450
600W PSU
EVGA GTX+ 275

I want to put in another card for just dedicated physx. I cant run a high end card because of my limited power supply so i was looking at the 8300, 8400, 8500. Will I see any performance gain from doing this or will it actually hurt my frames? Thanks for any help

I don't know why you think you're limited by your PSU. You could power another GTX275 with that

The GTX says on it minimum 550W power supply for just one so thats why.

You might get away with it as long as you arent OC'ing and have tons of Hd's, USB devices plugged in.. etc.

I'd get another GTX 275 or .... nothing. :beer:

Edit: What PSU are you running?

Ignore manufacturer recommended power ratings. They are (effectively) meaningless. you could power two GTX275's very easily

Have you played a Physx game that taxes your 275 enough to get below playable framerates? If not, there isn't any reason for a second card to run Physx. It might help to know which game and what res and setting you're using.
But, for the sake of example, I used a 8600GT to run PhysX alongside a 9800GTX+. There is actually an old PhysX FAQ that used to be a sticky with exactly these kinds of examples. Anyway, the 8600GT increased framerates in GRAW2 about 30% if I remember correctly.

Well I have cryostasis and I just wanted to prepare for the future.

hehe I'm using my 8800 GT as my dedicated PHYSX card and I see that my GTX 275 is benefiting but I didn't get that far before I added the second card. I wouldn't say the game was taxing my GTX 275 but I was just being proactive because my friend told it gave his GTX 295 a work out.
