SLI for me causes very slight lag in games like UT3 when SLI is enabled whether SSAA is enabled or not. I've got used to it and aren't getting lower frags online really, but it is not quite as ultra-snappy as with SLI disabled. Offline play though I wouldn't even notice it, you have to be really sensitive to notice.
