I'm debating on getting a 2nd amd radeon 6950 graphics card for my computer however i was wondering if when you try to play a game that does not support crossfire are you unable to play it and have to wait for a patch or does it just start up but only utilizes 1 card. Also are many games supporting crossfire set ups or only a bare minimum? I want to be able to play all games if i'm not able to crossfire might be out of the question for me.
Just uses one card. Most newer games support multi-GPU - if it doesn't it'll use the primary card. although plenty of games run CFX, it's more down to how they utilise it - BF3, CoD, etc, use it well, SC2 and stuff don't.
