Maximum resolution for this graphics card?

Check the Specs beforehand; Most LCD screens can handle a VERY high Resolution, so check what it can handle; then find out from the Cards Manufacturer what they say the output is, they MAY not know for sure, since some drivers I have bought for card have been able to produce A higher res for the card simply because it was a better driver, and used the cards resources better than was thought possible; In essence, you will not know until to drive it.
