According to Nvidia, you should only connect two cards that are the same model number together. Haven't verified this, just stating what they have up. You can hook together two different makes of the same card and it'll work fine. (a gigabyte gtx 580 and a zotac gtx 580 linked, for example.).

And I'll mention this again - SLI does not improve WoW performance, actually decreases it somewhat. (This occurs with a few other games as well...). I'd recommend buying one single beast of a gpu and rolling with that instead of paying much more for two cards and being very disappointed.
