I recently picked up an r9 270x card and I was really excited to throw it in, run a ferw updates and be on my way. Nope, never works out the way you want it to. I had my Radeon 6950 in before with proper drivers. I've alrezdy uninstalled and re-installed the latest drivers 10 times and the crossfire cable is on properly/GPU's are in both PCI-E x16 slots on my motherboard(Gigabyte gigabyte 990fxa-ud3). I must be doing something wrong. This has been driving me nuts all weekend and I'm currently very frustrated. I appreciate the help I can get.
