So I'm contemplating buying another Radeon HD 4890 to run it in crossfire with my other one.
I'm just curious; is it worth it? Will I have problems running some games at all, that don't support crossfire? Will I see a big performance increase in newer titles?
It'd kinda put me off buying it if it turns out I'll have to remove one card to play some of my older favorites, or have the performance drop in some games that don't support crossfire.

what games do you play? can you post your PC specs?
Well, games based on the Source engine, the Unreal 2 engine, Unreal 3 engine, older games like Half-Life and Deus Ex, even older games like Red Alert etc. There's alot. Potentially a lot of indie games or games that aren't as popular as the major titles as well.
I assume your screen resolution is around 1920 x 1080, is there a game you play that actually bogs down your 4890? If so a second 4890 will be more than enough.
You can also sell your current 4890 and get a 5 series, this way you dont have to deal with all the heat comming from 2 cards.
If you are not going to play new titles and you can care less about your GPU upgrade path I would recommend the second 4890. If not a 5850 or greater.
i wouldn't recommend getting another HD4890, that card on CF setup will produce a lot amount of heat... I think it's better to sell your 4890 and get a new HD5xxx, maybe HD5850, it would be great with your rig...
