GTX 470 SLI is it worth getting a 9800GT for PhysX? - Page 2

post #11 of 32
To be honest, even Mafia II, a single GTX470 is more than enough to handle it with everything pushed max, include Physx.
The answer is no.

Doesn't matter for physx.

It is not worth purchasing a separate PhysX card. If you already had an old Nvidia card lying around from a prior build, then it would make sense.

The answer is no.
I completely disagree.

A 470 will be very hard pressed with everything maxed out and physx.
Mafia 2 isn't very demanding, but everything maxed with physx? Not a chance.

I point you to here. You can see from his test, with everything on high and with no physx, a single 470 has an average of about 45 FPS.
Add physx to that, and you are pretty much expecting a choppy 30-35FPS, as physx is extremely demanding on this game.

Yeah, at stock I got an average of around 45 FPS, which was a bit low for me, and that was without physx running. I could add that into the graph if its of interest.

With a 9800GT running physx at stock the 470 was held back by it slightly, but even then with a dedicated card the average was only 40 fps.

Without the 9800GT frames would probably be terrible and probably below 30 fps average.

Just bare in mind that is with physx set to high and the file was unedited which means all cloth apex was present.

Well I'm talking about ingame FPS since I'm no longer care about Mafia II IG benchmark tool. Afaik, the most stressful part of mafia 2 physx is assigned to CPU, and from my little experience with single 480, the game run flawlessly at 1920x1080 with everything pushed max, rock solid 60+ FPS. And if a single 470 is only capable of producing such low FPS, I think I've got a 470x2 in GTX480 form which makes no sense at all, right.
Anyway, I don't have any GTX470 here to confirm my hypothesis so I could be wrong or right, who knows. I abandoned this game few months ago and maybe there was an update that makes my hypothesis outdated

If you can, yeah. It would be great to see how you compare a 470 with physx on it vs a dedicated card.
It would give perspective on how much a dedicated card can help.

even with physx in Mafia 2 you can either do the tweaks to be able to play still with the eyecandy stuff..



Just don't Buy a 9800GT for a purpose of using it as physx over your 470 SLI
