Dear Friends,

I am NOT a tech geeks like you are, I am just a game lover.

Just a college student with limited money so can't afford expensive cards.
Most of my hardwares are high-end but 2nd-hand.

I have a question choosing a right-budget card for PhysX.

When we pay our favorite game, if we see that the FPS is dropping too much, at that time we look for upgrade that fit our budget.

How to buy a card for PhysX ?

I mean, there are gamers who buy top of the graphics card for PhysX.
But, I am sure that, most of us can't do it, isn't it?

So, what card do you suggest for PhysX ?

Well, "the faster the better", but really it depends on many factors, like amount of money you want to spend, performance you want to get, noise, power consumtion, etc.

High end GPUs like GTX 570/580, GTX 660Ti/670/680 should be enough to play with maximum PhysX effects on a single card, in any current GPU PhysX game.

As for dedicated PhysX GPU, most common choise would be something like GT240/GTS450/GTX650.

However, there are several recomendations:
1) Don't fall for buying cheapest dedicated GPU possible (something like GT9400 for GTX680) - it will only bottleneck your system, resulting in lower fps than using single card
2) It is also unreasonable to buy high-end GPU for PhysX only (something like GTX670 to pair a GTX680). In this case, two GTX670 in SLI will fit better.
3) While choosing a dedicated card, look at amount of CUDA cores and GPU clock. Memory amount is not that improtant (512 will be enough).

And here some benchmark links:

Actually, I own an original DELL Ageia PhysX card PCI-Ex v1.
I bought it when it was a HOT stuff.

Then I switched to a ATI Graphics card which blocked my PCI-Ex v1 slot.

Now I am want to setup a new system.
I currently have a nVIDIA GTX 550 Ti 3GB Card.
Going to setup the system around it.

It has no use nowadays. It is not even supported by latest GPU PhysX - Metro 2033, Mafia II and above. No to mention that its performance is inferior in compariosn even to low end GPUs.
