Well, first, there are some questions you should answer to give enough information to give you the right idea.

[*] What resolution are you typically working on?

[*] What types of things do you typically use your PC for?

[*] If you play games, what kind of games do you typically play?

Then, second, this is a general information thread about SLI/CFX to help people with general info about multi-GPU setups. You would be better served posting a thread in the GPUs forum specifically posting the above information I advised you to list to get a proper response.

Pair a GTX with an RTX? No. I don't ever see that happening. NVidia has always been very restrictive on what will SLI together.

Up until super recently they were't even going to allow GTX cards to do ray tracing. They changed their mind recently. I'm not sure they opened up ray tracing and SLI. Considering SLIs performance recently if I were you and looking to do ray tracing I'd be focused more on getting the best RTX card you can. I strongly suggest waiting for Ray Tracing games to show up however. So far there isn't much you can do with it.

He might be thinking about how PhysX could be performed on a 2nd card, even if they weren't the same. At this point, I've not heard of this being a possibility, and let's just be honest, it's not going to be worth the money, even if it did.

I made mistake a small one, purchased evga 2080tiftw3 and asus 2080ti oc (bought the cheapest in auction), what i did not know or research was the height and length differrnce, length i have no issues but with height evga is taller and hence when install nvlink it slants down a little but everything works ok in sli and my question is how to equal the height, is there like slot extender tool if any i could use, just want know if therr is such a thing, thank you.

You may have to find a flexi nVidia link. I'm 100% sure I've seen some, but I don't know if they're sold separately.

Cheers!

I have a Sapphre R7 640 2GB video card. I don’t know what it is AMD graphics or if sapphire is another video card brand but I am trying to mix the vram of 2GB from this card with my msi GTX 980 4gb video card

Maybe it’s a stupid question but I’m not good in computers. You may say this R7 gpu is bad and obsolete however I really don’t have use for the card and I want to use its 2GB as extra vram for my virtual machines. I know it’s worth $10-$20 but I’m not willing to buy a high end gpu with my gtx already being Gigi enough to play games.
