Radeon and Geforce in one system

[102nd-YU-TazMan]

Soon I will be upgrading my graphics card to 670 and will have a spare 6950. I am running a two monitor setup. Since I don't necesary need to sell it and have no second computer I was wondering if it would be beneficial to keep it in the system in another PCIe slot and use it to drive second monitor? From what I read on Google it is indeed possible to have one radeon and one geforce in one system and use them to drive two or more monitors for extended desktop in windows. My question is if I export TAD and TGP on that second monitor being driven by my old 6950 will I notice performance improvement coompared to scenario in which both monitors are driven by one graphics card? Will this setup be more futureproof if I decide to run multimonitor setup (4) at some point?

Your 670 can drive 4 monitors right out of the box with no problems. I run 4 monitors off of a 4gb 670 with no problems at all and good fps. I even export viewports to my 3 touchscreens. I run in windowed mode with a res of 4080x2160. I have also used this configuration using softTH but am not currently using it that way but it is another option.

Introducing a second card along with a whole differrent set of video drivers is just asking for issues. Here is a quick video of my setup:

No. You cannot drive 4 monitors with a GTX, only three. You need to purchase another hard-to-find display adapter to get the fourth. Be sure to order one with your card.

My question was more of an academic one. Just wondering if this secondary card (how the system chooses primary one ???) is only used as a simple 2D frame buffer and its rendering pipeline is never used?

 

I have some OpenGL programming experience and I can't see how could I use secondary graphics card to render another view of the same scene (TGP or MAV view for example). I guess in DCS this secondary graphics card is used purely as 2D frame buffer but maybe someone with more detailed knowledge of DCS internals could clarify this.

Second video card running monitors for export will not give any higher FPS, it will be used as by-pass only (all rendering is done on main video card) so you're better off running second monitor off the main card.
