Thinking of getting another Pci-e 6600gt and SLI board

[AMDCrazy]

As the title says. I already have a 6600gtPci-e from evga and would like to know if I can get a different manufacturer and run with mine in SLI or do they have to be the same. Want to go to SLI for better overall performance and overclocking not to mention a lot better video. Let me know your thoughts on this. Thanks
