I currently have a EVGA nVidia 8800GTS 320MB and was thinking of buying another card. Can I just add another card into my motherboard and get it to work. I was looking at a 8000 or 9000 series 512MB card.

From the amount of what I have read, the answer is maybe. It would be best to read both cards specifications and maybe even emailing tech support and ask

In order to be able to SLI, you need two or more cards with the same graphics core such as G80, G92, etc. You can mix and match cards with the same core, but the speed of the cards will default to the clocks of the slowest card. For best results, you should use the same card in all slots.

This is what I've read. With ATI's new generation Crossfire cards I believe you can mix different GPU's. With SLI though you can use cards by different manufacturers, but the GPU's must be the same.

What everyone stated is correct. To do SLI, you would need another 8800GTS 320mb or 640mb. The thing is since you already have a 320mb version, a 640mb version would be a waste because it would only detect it as a 320mb card also.

With ATI, the 3850, 3870, 4850, and 4870 are all interchangeable in crossfire because they are very similar chips, and use the same drivers.
