Anyone run an nvidia card alongside an ATI card without problems?

This is probably a tall order, right now I'm thinking about having two hardware profiles with the other card disabled...but it would be ideal if I could just choose which card to use for a game without rebooting.

I may have to do some experimenting.

why would u want to do this?
no card is better in 2d apps.

and i dont think its possible to reload graphics drivers without rebooting

I think we wants to be able to switch between ATI and NV cards for different 3D apps, not one for 2D and the other for 3D.

Because old games work like crap with the 8800gt (or newer ATI series cards) and its gpu scaling features don't work...but its faster then my x1950 card for new games.

I tried doing this in windows vista x64 with my 8800gtx, because the 2nd DVI port wasnt working correctly...

it wouldnt work at all, the ati driver wouldnt load because the nvidia driver was loaded first and whatnot... i honestly could never get it to work.


i was able to get the 8800gtx to work flawlessly with an NVS-290 i got on ebay for $45..

well the drivers will work in harmony, but how are you planning on taking the card out and putting the other one in without power issues as well as the .dlls and drivers loading for the card, and how you plan on giving juice(power) to a card straight up and without damaging it, wont plugging summin out and plugging another in blow the circuitry? or is it hot swappable?

It's not possible on Vista, and you won't have much better luck on XP.

This was a while back but I had my 8800GTX running as my main card on my eVGA 680i (sli board). I decided one day to add my ATI X1900XT in the second PCIe slot. It booted up -- I installed the drivers and heck it worked. I had a second monitor plugged in to the ATI. The funny thing was that when I tried swapping out the ATI for an older Nvidia card (7800GT I had lying around), it crashed over and over again and I could not get it to work. I don't think this is what you are trying to do... I was just trying to see if I could get one card to do something (have it play my main game) while the other was doing something else. Although the configuration worked, I never did figure out (if it's even possible) to tell a second card to do something else -- but I assume that at the very least the GPU work was being done on the second card (ATI) for what was displayed on my monitor connected to it.

WinXP pro btw.

Heh...there is no hot swapping. My motherboard has a second pci-e 16x slot (its only 4x electrical but it works fine).

Yeah, I've had it boot up fine with drivers for both installed...however I haven't gone any further then that. I've got a test drive to try out. But I think the one or the other solution will be enough.

Now that is summin interesting that i never took into account, nice thread guys, flip i really never knew that, and will each GPU control its own "windows" essentially? so like multiple desktops in essence?
