GTX 560 Ti + 9600GT for PhysX (PSU Question)

post #1 of 9
Thread Starter 
Hey there,

I have a GTX 560 Ti as my main video card and I want to install my old 9600GT as dedicated PhysX card, my question is: Is a 750watt PSU enough for powering these two cards?

Definitely. You should have no problem running the 9600 as a PhysX card.

750W is PLENTY. Also, beware of a slight bottleneck since the 9600GT only has 64 CUDA cores.

On an afternote - the 560 Ti may be faster without the help of the 9600. The 560 can process both PhysX and visual graphics faster than the 9600 can process PhysX alone. I recommend you run some benchmarks and compare, to see which one is better.

334 CUDA cores with only a dedicated 64 CUDA from the 9600GT might not be in your best interest which is why I didn't do it with mine and used my GTS 250 instead. It may still help a bit but if you had a 570, it would be a bad idea. A GTX 480 with a 9600GT for PhysX see's a very small gain in some benchmarks (Mafia 2 bench)

In some cases, it could either make or break your FPS depending on how much PhysX is being used in a certain game.

Although, if you're a folder, you can just leave you're 9600GT set to GPU2 fold while you play a game. Kill two birds with one stone! wink.gif

384* actually, which makes it that much worse. biggrin.gif

That 9600 will probably hamstring your 560 pretty badly.

Corsair 750 is plenty for that setup.

Oops my mistake I forgot sorry! Your true that's even worse. lol I personally wouldn't use anything less than a 9800 GTX+ or GTS 250.

But like I said, it would be useful to have in your rig to just fold on while you do other stuff just don't set it as your primary PhysX card. Even though an average WU for a 9600GT takes around 3-4hrs, why not? It's still points and helping out the good cause. biggrin.gif
