2 different GPU's in one system?

[Dubesta11]

I have a GTX 660 and a GTX 650ti Boost, is there any way I could put them in the same system and make it somewhat faster? Not SLI, but like having a separate Physx processor? I don't know what to do with it.

You could use the 650Ti as a physx card

I know, but could it have any other uses?

I know you said no sli but if they are both sli capable you could do that

You can put them in the same system, but you can't use them simultaneously for the same task. 

 

If you have a dual-monitor setup, you could theoretically use one to drive videos/etc on your secondary monitor, so that your primary GPU can fully work on running a game on your primary monitor without having to waste some of its power on the video.. I haven't done this nor have I done any research about it, so it's just a guess on my part.

Unfortunately you can't SLI different GPUs.

And the point is??

 

He has a 650TI and a 660, so: No, they can't be SLI'd (unless you use some hacked drivers or something similar).

 

You can SLI/CF different brands of the same GPU

You can Crossfire (not SLI) different AMD GPUs, but only if they have the same class of chip, like 280+280X, 290+290X, 7950+7970, 7850+7870, but never if they have different chips, like 280X+290X, 270+280..

2. With nvidia no,

Not exactly correct. I have seen 670 and  760 in SLI and they are not the same.

they are wrong, or that guy that did it has experience and tooling to make graphics cards.

The 760 is based on a modified version of the 670. If I remember correctly, SLI compatibility between those cards wasn't intentional, and Nvidia patched their drivers to remove compatibility between those two cards.

Also: some people have hacked the driver software to trick the system into running the cards in SLI even though they're officially not compatible. 

 

Going back to the OP's situation: 650TI and 660 are not officially compatible. End of story.

ok thanks I wasn't trying to argue or anything

You could use a separate card for a separate monitor?

I'm pretty sure you can.. I have never done it though, as I've never had any rigs with mismatched GPUs..

Also, the performance loss when you have a video playing on a second screen is minimal, so there isn't really a huge reason to do something like that.
