Suggested graphics card upgrade for my computer

Not sure if you can mix and match AMD/ATI and Nvidia cards in a single system, but I never tried.

The only need to have multiple video cards (other than SLI/crossfire) is to run more monitors than the primary GPU is capable of supporting. I have a similar setup, same CPU, same chipset etc. I run 3 graphics cards, and 6 monitors. Whenever I'm gaming, only the primary GPU actually renders the graphics, the other cards just output the frames created by the primary. Only when I enable SLI (and thus lose 3 of my monitors due to SLI not supporting multi monitor other than surround, which my monitors do not support) does the secondary GPU get utilized.

Since the new GPU you ordered is way ahead of the old one, I would simply swap it out, and keep the old one for a spare/backup.

So based on the above, are you saying the any crap card will work for additional monitors and that the main card is doing all the processing and the seconday card is just displaying what it processes???

No. It doesn't work like that.
If you have more than one card, then each card will process whatever is output from it, unless you have Crossfire/SLI, which is NOT recommended for boxing.

It's also worth noting that you need Windows 7 to mix and match cards from different vendors, from what I've been led to believe.

So I just got my 7970 delivered this morning, based on this post, I should be able to run my main account on the new 7970 card which would only have a single game processing load? And the older 6970 card would do all the processing of the two monitors my slaves are shown on? Correct?
Effectively providing similar performance to soloing if I exclude cpu and memory demands on the system for the extra accounts?
