In theory, either card should work, but you may have stability issues. SLI is a lot more finicky than Crossfire is, so I'd recommend sticking with the same brand, and if at all possible, the exact same part number. This ensures that you won't get any nasty surprises.

As far as performance goes, I don't think I've heard of mixing brands causing degraded performance.

Everything I've seen would suggest it's the other way around, with SLi they just need to be the same GPU and preferably the amount of RAM should be the same.
