PhysX Dedicated cards. What card do you need?

7800gt is better.You go by the second number in the model number,not the first.The first number is just the series,7000,8000,9000.7800GT is the second from top of the series.9500GT is at the lower half of its series.

 

8600gt /9500gt is slower than the 7800gt. id say get the 9600gt taht one is good

 

Ah I see. That's very helpful. Thank you. So the 9500gt is kind of a waste then coming from a 7800gt?

EVGA 512-P3-N863-TR GeForce 9600 GT 512MB 256-bit GDDR3 PCI Express 2.0 x16 HDCP Ready SLI Supported Video Card - Retail This is $105 - but $85 after a mail in rebate.

 

I've run an eVGA 8800GT 512MB card as a single video card that also does PhysX and I found it lacking in Unreal Tournament 3 PhysX maps (30FPS some times lower). That was on a Q6600 / P35 system. My new Core i7 system just got an upgrade from an 8800GTS 640MB card to a GTX260 and that thing rips into the same Unreal Tournament 3 PhysX maps hitting the ground running at about ~160FPS.

You don't need a dedicated PhysX card. All you need is a decent single card solution and it will do PhysX and video just fine.

Like the question with respect to SLI, just buy the best single card that you can afford. Then if you want more go SLI or dedicated PhysX.
