Have any one paired different types of graphicscards in SLI as I like to do with ATI RadeonHD 5750 with Nvidia Geforce 8800GT.Is it a dangerous experiment to risk my computer

It simply will not work, 8800GT will only work with 8800GT and so on.

absolutely NO, you cannot pair them at anyway, SLI/CF works with identical models with different vendor sapphire hd 6870 + MSI hd 6870 = crossfire if you change one of the model like hd 7770 so it should not work same story of NVIDIA sli asus gtx 670 + msi gtx 670= sli.

You have to look the model that should be identical brand doesn't matter.

Well have fun trying. I don't think anybody knows what the out come is if you try and the people who have tried in the past they never got back to us to let us know and haven't seen them since.

We will never know if it blew up there rig for fried it or burnd there GPU's. All I know is I would never ever do something like that. Good luck to you.

well for a more fuller answer sli is for nvidia based cards while crossfire is for amd so you can't bridge them together anyways (the bridges are not the same)=.=

sli/cf will only work with identical cards well to be more exact you'll want the core clock, cuda cores and all other specs the same in order to use them in sli/cf, so the drivers won't allow it and even if you do manage to get them working they will end up bottle-necking each other

I have seen it done only twice, and I think it was just pure luck and ignorance of what they were actually doing. SLi is very specific on what it wants to be ran in tandem with, in fact it wants to run on the exact same counter part. Where as Crossfire you may have a little more give on what you can technically run in tandem with your original card. (i.e. a 7800 AMD graphics card can generally work with other graphics cards in the 7800 series, as in crossfiring a 7850 to a 7870.)

As far as the risk factor goes, don't do it. It is extremely difficult to pair two different NVIDIA cards, even two identical cards from different manufacturers sometimes! It can (hypothetically) be done; you can write some software to make them work with each other, but you also need to engineer a corresponding cable that links their different bridges together. If you don't want to go through all of that for something that may or may not work then don't try it, but if you want to then go for it. I would love to see something like that! :D

You use crossfire for AMD/ATI cards, and SLI for nVidia's. And then there was Hydra 100/200 from Lucid Logix, and I think you can do it. If you can find a mother board (e.g MSI BigBang or Asus Crosshair 4 extreme), it would work though. Not sure if Lucid has the latest board, but if you would just like to have fun, then I guess this is the way to go.

However, using a board that is not Hydra supported, you cant'.

Best thing you should do is;
1> sell the other card, and buy a new one similar to the one you want to crossfire.
2> Or sell both cards, and buy a latest graphic card (e.g. HD7870 or HD7950, or GTX670 if your and nVidia user).

Wow, I never heard of Lucid. How reliable is it?

simply NO. Only works with same models OEMs maybe different though. For AMD it's called crossfire(CF) and SLI for NVIDIA.

Read the articles. It should tell you. I recall them not being reliable, but in some cases it did offer improvements. Of course microstutter was not measured.

It wont work. The cards have to be identical to be in sli or crossfire mode. For example if you have a gtx 660, to have sli it will ONLY work with another 660. Same goes for all cards
