Thread Starter 
So XFX just released a 2gb version of the 6870 will it work with a 1gb 6870 in crossfireX?

If the memory controller doesn't cause issues it will work, do some more research and check if memory is at same clock latency and control ping

Yes, but you will be defeating the point of getting a 2gb card in the first place! SLI or Crossfire will utilize the memory pool of the smallest card, thereby wasting the 2gb.

Probably. But memory is mirrored. You'd only have 1GB of memory the other GB on the new card would sit idle.

Waste of VRAM, you'd need two 2Gb versions.
