can i have three different gpus running at the same time with different drivers for each on one operating system like windows 7

no

Yes, if one is nVidia, and one is ATI... or one is intel... (or some other compatible GPU.)

No, if you are suggesting using two ATI cards... one using v12 drivers, and one using v11 drivers... (Both would have to use v12 or v11 drivers.)

Can you be more specific about the "two cards", and which "two drivers" you are talking about?

im planning on using an additional 7950 i have a 7950 msi installed and i would either like to add a 7970 or another amd 7950 if possible

i recall someone on here manually installing a driver in windows, through the device manager. (i think it was in the thread about getting 6 gpus in windows)

Could this not be done the same way? Find the card you want and manually install the drive you want for THAT card.
(i'm definitely not trying it)

i figure windows would throw all kinda of errors if you had too many types mixed, IF it actually worked.

The only driver you need for ALL ATI cards is "catalyst drivers"... No special manufactures drivers required. (There is only one manufacture AMD.)

Eg, there is not a separate 7950, and 7970 and 7990 driver. They are all the same driver. (The OLDER ones for the 7950 might not identify the 7990, but the drivers for 7990 will have settings for 7950.)

One brand being MSI, one being HIS, one being PowerColor, one being AMD... has nothing to do with the actual card, other then bios-settings which have nothing to do with drivers, or specific hardware components, which also have nothing to do with drivers. (Unless they added a "special" chip to the board, which none have done... Or they have "tweaked" the original drivers for some "game" special performance... than there are only one set of drivers you need... catalyst drivers.)

Drivers are just command-lines, which windows or linux uses to talk to the card, and get info out, or tell it to do something. Drivers don't actually control the cards, the bios does that, and controllers. Drivers just tell the programs where to listen for output, and what to say to suggest commands. The catalyst drivers simply give the user additional controlling suggestions, for how the card should run, but the card does most of the "telling you what it wants to do". (They give us super constrained limits that don't normally do much damage, if pushed to a limit. "Normally". lol, we don't run these cards "normal".)

You should be fine with the latest catalyst drivers, and latest afterburner-beta.
