It should be able to, yes. It's performance should also be quite adequate at your resolution. It supposedly overclocks well, too. You may not be interested in that feature right now, but you might later on when the card gets older and doesn't perform as well with newer games, or if you end up getting a higher-resolution monitor down the line. ATI's drivers also feature built-in overclocking, up to a certain point.
Told you that I didn't know very much about Hybrid Crossfire.
