help with my mobo + Graphics cards

post #1 of 9
Thread Starter 
Hello OCN'ers,

I am about to buy a new graphics card (probably an MSI 6870 twin frozr II) and i was wondering if i would be able to use my current GTS450 as a dedicated physx card, would this be possible?

OOPS, by the way the motherboard in question is the one in my sigrig

I know that it only has 1 PCIe 16x lane but i am fine with the physx in a 4x lane.

Thanks,

#Fibre

You should be fine. GTS 450 is enough power for physx. I think a GT 240 is the minimum.

Are you sure thats it ok to mix two different types? (for example nVidia and AMD?)

Thanks,

So i would just have to move the 450 to the 4x lane and install the 6870 in the 16x and im ready to go?

It takes a little more than just plugging it in, I remember when I did it it took some tweaking, a lot of opening and running fluidmark to see if it was working then closing and messing with it some more but that thread will help you loads and you will get it.
