I have a new compunter with a GTX 970 wich use Nvidia driver 353.06 and I want to use my old GTX 280 wich uses driver 341.44. The problem I've is that the drivers overwrite the other so I can only have one of them installed (and on of the cards running) at the same time. I had installed the drivers manually through windows device properties.
Each driver doesn't inlcude the others architecture so I can't use only the latest driver versions.
Can I install both drivers in any way? Something like install one, rename it and install the other?
I see other similar questions but in both they can really use the newest driver.
I know that it will be worse than using the GTX 970 alone but I still want to try. it.

Unfortunately, what you wish seems impossible unless you have some guru-level programming and OS knowledge. The GTX 970 driver only supports back to the 400 series. Basically nVidia would have to make a conscious effort to merge support of the 200 series into the current driver. I would imagine it would also increase the driver size to over 600 MB. Good luck in your quest but overall I too think that the PhysX delivered by the 280 will actually hold back your 970
There was a video I saw of a GTX 580 using a 8600 GTS for PhysX and the FPS drop was substantial vs. just running everything on the 580. I cannot find it though :(

Here is a solid run-down: http://www.volnapc.com/all-posts/how-much-difference-does-a-dedicated-physx-card-make and this picture specifically http://www.volnapc.com/uploads/3/0/9/1/30918989/7654086_orig.jpg. Unfortunately the blog does mention using a 200 series with 900 series so I question the credibility.
