Hello!

I have two cards here. The one is not in-use.

Will it be possible to make them in "one"? Or does they have to be the exact the same! It's Nvidia GTX 280 and 260.

Best Regards,
FredeGail

I belive in Nvidia's case they might have to be the same

I know and understand with ATI tech. you can use one higher and one lower Gpu

example like 5870-5850 x-fire

Nvidia might be able to do the same but since i changed brands im not to familliar anymore let's hope some of the members have a good answer for you

No. They have to be the same GPU type. I'm not sure whether they must have identical VRAM quantities, or whether a mismatched pair would operate at the RAM level of the lesser card.

FAQ

"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."

Some people use a second nVidia graphcs card as a dedicated PhysX processor, but I've never tried it.

If you already have both the cards, I'd use the 260 as a dedicated physx.
