I'm a little confused....I just paired my 4870 512 in crossfire on my board....Sandra says I have 2x ATI Radeon HD 4870's as my primary adapter. Win 7 only shows 1 display adapter with no details. There are 2 instances of this card in Device manager....ATI's site says there should be 4 instances of this card in devicce manager if it's installed correctly. I've enabled crossfire in Catalyst 9.6. How do you tell if Win 7 recognizes both cards?
