View Full Version : Can you SLI two different cards?

So my GPU is defiantly my bottle neck in my system, it's an older GeForce 9800GTX. I'd like to pick up a new one and I was looking at the GTX 260. Seems like a good price/performance. This card specifically
XFX Nvidia GTX 260 (http://www.newegg.com/Product/Product.aspx?Item=N82E16814150398&cm_re=gtx_260-_-14-150-398-_-Product)
Now, can I take that and SLI it with my old card? Or does it have to be two or more of the same card to SLI? I figure I have an extra pci-e slot on my mobo, and it would be better than just giving the old one away or even worse throwing it out. The $199 fits my price range perfectly, but buying two probably can't happen. Gotta buy books for next semester :p. Also, any other suggestions for card brands?


Intel i5-750 quadcore
4G DDR3 1600
Nvidia GeForce 9800GTX (512Vram/cache)

It is not possible to use SLI on those 2 cards!

For Sli to work the GPU Core needs to be identical, possibly the same rule for its memory, but the speed of either gpu or memory can be different between 2 cards.

Also, exactly what kind of motherboard do you have, not all i5 motherboards support SLI.

Edit: Instead of looking at the 260, have a look at this EVGA GTX460 (http://www.newegg.com/Product/Product.aspx?Item=N82E16814130571)

Ohhhh ok thanks for that info. I'll check that other card out then cause if the whole SLI thing isn't gonna work anyway I can go outside of Nvidia.

They have to be from the same series but not exactly the same. You could SLI an EVGA and XFX 9800GT but not a 9600GT and 9800GT. I don't think the memory has to be the same, like you could use a 1GB and 512MB card but I'm not positive on that.

With the new lucid hydra chip you can use two cards to gain a performance boost. But at this point it's AMD only

You can only SLI video cards with the came name, aka 8800 GTX with 8800 GTX. You can't SLI a 8800 GTX with a 8800 GTS or 8800 GT.

Can I mix and match graphics cards that have different GPUs?
No. For example, an XXXGT cannot be paired with a XXXGTX in an SLI configuration.

No. For example, an XXXGT 512MB cannot be paired with a XXXGT 1GB in an SLI configuration.

This does in fact work. But to use the chip you first have to fork the gratutious amount of money ($300 is a lot for me) for the motherboard with the chip already on it.

As I understand it the chip translates the code coming out of each GPU separately. Something like that.

Lucid Hydra IS not CFX or SLI you can mix any GPU you like, no CFX/SLI bridges needed...

Cool thanks for the answers everyone, I knew what it was and what it did, I just wasn't sure of the specifics. Looks like the SLI is a no go for me with my current card anyway. Guess I'll just grab a GTX 460. I need the upgrade pretty badly.

You could dedicate the old card to PhysX though.
