    obviously more arguments to be made for going with the Nvidia Physx card they're starting to, but I was curious as to whether or not it's worth putting a 2nd 48XX series card in my system

    I currently have a 512mb 4870, would getting a 1gb 4890 give me significant enough gains to consider dropping the coin?

    Depends on the resolution you run and what games you are playing.

    And you want cards to be the same. Crossfiring different cards is a bit inefficient.

    For pure geekery factor, multi-GPU is cool. It has its drawbacks too - power draw, noise, scaling inefficiency. It would almost certainly be a better idea to get a 5xxx-series card (5770 or higher) and sell the 4870 to recoup some of the cost.

    I wouldn't bother, as many games don't support it (i.e., WoW). It's benefits are no so large as it wouldn't be worth the price. I would look to a Solid State Hard Drive for a far superior upgrade.

    Don't bother. You can improve your system performance more by putting a badass RAID controller in that second card slot, and hooking up 2-3 hard drives to it in a RAID array.

    1920 x 1200; I've mostly played MW2 and TF2 lately. I've got a few games I play (GTA4, Farcry 2, Red Faction Guerilla, Company of Heroes, Batman Arkham Asylum, etc) less often that would benefit from having a 2nd card.

    As for people saying I need to keep the same card, it only has to be the same series. I can clock my 4870s memory to the 4890s speed and it'll work just fine.
