Current Build:
ASRock Extreme3 Gen3 Motherboard (2 PCIe 3.0 slots)
Intel i3-2100
Sapphire Radeon HD 6850
500W OCZ PSU

Some future and recent games I have looked into have rather nice Physx integration (Borderlands 2, Arma 3), and I would like to pay for that upgrade.

My questions:
1. Are there any other advantages towards having a separate, cheap, Nvidia card for PhysX?
2. Will I experience many problems with software/hardware compatibility?
3. Would a change to a 550ti Fermi or similar card prove better?

I believe that the requirement for PhysX is 96 CUDA cores. If there are any other restrictions I should be aware of, please mention them!
:??:
 
Solution
It depends really on the card you purchase. There is a Physx mod out there (which I've done and will probably do again soon). Seeing as you have a 500W PSU, you are somewhat limited in your choices.

You could probably run a GT640. You could also get an old 9800GT which would be fantastic.

If you go too cheap though, you won't be able to run any games. My hacked drivers worked pretty well actually.

1.you won't see any performance drop at least from your main card that's used to run the game

2. you're gonna be needing a hacked driver if you're going to pair an AMD card with an Nvidia card as a dedicated PhysX card. while many users here have stated that they have no problem with said drivers, i'd rather side with caution, nonetheless, and tell you that while they do work, don't expect them to work 100% of the time.

3. a cheap GT 430 will do you good, a 8800/9800 GTX would be great if you can find any.

I'd heed what hazle says. I'm unsure how these hacked drivers work they update physx frequently. Borderlands 2 is a pretty new game but runs on dx 9 so the physx side may be pretty lax on requirements either way if you want the extra eye candy I'm sure you could buy one of those cards and use it in tandem with a hacked driver or fork out the money for a gtx 600 series card 660,670,680 and use physx.
 
Well, when I was using it, I was using a 9600GSO, which is a bit slower than what I usually recommend, which is a 8800GT/9800GT. Performance wasn't too bad on it though.

I would recommend the new drivers, but since the mod does not work with them, it won't operate correctly.

It was with a 6950 and a 9600GSO when I used it. Then for a short short time, I used a GTS250, which worked great with the 6950 until the 6950 started overheating too much in my new case (Antec Sonata) which is when I switched it out for my old GTX460, which runs Physx awesome.
 
I hear reading around that some of the older cards have issues with physx maybe a gtx 640 or 650 shrugs. With borderlands 2 sorry I haven't seen anything with batman arkham city that game is really rough on even nvidia cards in phsyx.

Yea Arkham City is pretty hard to run for even modern systems. Borderlands I don't mind playing the Physx on medium, as it still looks pretty good anyway. And in the case of Borderlands, you are more playing for the storyline and the utterly hilarious comments made by the characters instead.

That's much better than my current main build lol. I'm using my 6950 in another build so it has more airflow. My plan is to get a new fan for the 6950 and get it back into my computer, so I can have better results in gaming as well as all sorts of programs, such as Solidworks and CAD and Visual Studio, which I use for school.

That's interesting...
Currently, with my RADEON 6850, I am able to use physx on medium without any major drop in performance during combat (putting it on high will take my FPS down to 10-15 at times).
And with all this talk of 'Hacked Drivers' I don't think I would like to be buried in software issues.
I think I'll just wait and eventually upgrade to a GTX 660 or better when the money becomes available. I believe I have plenty of friends who would appreciate an upgrade to a 6850 anyway :kaola:

Haha I do realize that in order to run the anticipated Arma 3, I will likely NEED a processor upgrade.
I have heard rumors that Arma 3's PhysX will be controlled by only your processor, so that might take a higher priority in the long run.
Sandy Bridge 2500k or similar will probably be my choice, due to their decreasing prices and because of Ivy bridge's heat problems.

March 29th 2013 is the estimated date.
I could probably get in on the closeout sales near the beginning of next year.
You think an i7 would be more efficient in Arma 2/3? I always hear that 'Quad core is enough' in gaming, but Arma seems to be the one setting the bar for processor dependency.
