Worth getting a card dedicated to physx?

post #1 of 9
Thread Starter 
I'm wondering if I should get like a gtx 260 or 460 and dedicate it for physx? One other question, if I wanted to run SLI, I need 2 of the same cards right?

Sup, Yes it has to be the same card and preferably of the same brand though with the latest drivers you can use different brands. if you cant run SLI it does help to have card dedicated to physx... I have that set up right now because my mobo does not support SLI only crossfire.. no biggie.. have one 9800gtx and other as physx running perfectly.

only if you actually play Physx games. (Not alot are even out)

Me, I would say no, unless I already had an Nvidia card before my ATI then yes i'd use it. But if you planning on purhcasing one just for physx.. no.

A physyx dedicated card is only useful in a handful of games. I also did quite a few bench tests, and it was actually better to have the better card run everything. Reason being, The card with more cuda cores will wait for the physyx card to complete the computing and send it through the SLI/crossfire bridge. Using a 460 + a 9800gt, both overclocked yielded a lower physyx score by quite a bit vs. using only the 460 in vantage.

Personally I don't really see that much of a point really. Barely any games use it, and the games that do usually are single player so once you've played them you don't really go back to them.

You'd notice a bigger improvement from a SSD or something IMO. Better yet, put that money towards another 570 and you'll definitely see an improvement

The 580 can handle 99% of the games maxed out with physx, so I don't see how the GTX570 won't be able to.

If you had a spare card lying around and collecting dust then yes but if not like others have said the gtx570 will handle it fine.

Seems like a lot of people are just keeping their old cards when they upgrade and using it for PhysX. With the amount of games that utilize the PhysX APIs, very few, and the power of recent Nvidia cards, very high, there is little or no reason to do the dedicated route.
