It is not possible! Start with one card if not happy you can add another for Crossfire just make sure your PSU can handle it.

You can't crossfire those cards. Really the only time you want to crossfire is with two of the same model (two 6870's, two 6950's, etc). Some other combinations are compatible but it's grossly inefficient and a waste of money.

As far as your situation, I'd take a look at the games that you're playing at your resolution and see if you're happy with the peformance. If not, crossfiring is a cost effective way to boost your performance. Could you provide us some more info about your system, the games that you play, and your resolution?

Be aware that there are POTENTIAL issues (driver problems, higher power requirements including more PCI-e connectors, and "microstuttering" that some people are bothered by). That being said many folks are very happy with their CF systems.

For your resolution a single HD6870 should be plenty!
