So here is my problem... I have 2 ATI Raedon HD 5770 made by XFX (Trusted Brand) and my motherboard supports Crossfire X. When I go into CCC (Catalyst Control Center) It only shows 1 graphic card. I have the little bridge thing to connect the 2. In Device Manager They both show up. I am Running W7 X64 bit. I have 8 GB of Ram and soon getting 3 2 TB of Space to put in Raid 0. right now i have 500gb of space. My motherboard is a ASUS M4A88TD-V EVO/USB3
Yeah, even though they both show in the device manager it would be a good idea to make sure they both play games well on their own. Also make sure there are no options in the bios for dual cards. I don't know if that is done nowadays but it used to be. It has been a while since I have had dual cards.
