Is Hybridiz Phsyx worth it? What are downsides?

Ok so i have a sapphire 7950 oc ed and wandering if I get a cheap 9800GT and dedicate it for PhysX if I can play games with PhysX on high.Like is there any performance trade offs/issues???? OR would I need something like GTX 650 because if that's the case $100 for PhysX isn't worth it.

Surprisingly, geforce.com has a good writeup about PhysX performance in a modern game (Borderlands 2). Scroll down to the performance section and you'll see that you need at least a GTX 460 to get reasonable performance.

He's talking about a hybridized setup.

I had a hybrid setup for Borderlands 2. I later decided to disable it. I just wasn't getting the performance I wanted. Although it iss due to me having an older system.

Processor: Q9550@3.6
Mobo: P5Q-E (only supports two cards at 8X each)
Primary ATI Card:XFX HD 6970 @900/1400
Physx Card: EVGA GTX260 Core 216
Intel G2 40gig SSD

While playing, the GTX260 was seeing only 40-60% usage during huge Physx intense scenes.

In doing my research beforehand, the 9800GT looked to be more than good enough. I only got the GTX260 because I got a great deal on it. ($30)

Here's the thread.
