Problems with XFX 6850

[JoshNYC]

Thought I got a bad card but NewEgg overnighted a replacement to me and I'm seeing the same exact issues. See garbled video and can't reach BIOS. Works fine with GTX 460. Have tried everything (pull out RAM, disconnecting drives, CMOS reset, BIOS update, different PCI slot, standing on my head, pulling out hair...).

Anyone have a working version of this configuration (P67 PRO with XFX 6850 dual fan)? I'm beginning to think they're just not compatible somehow...

I realize that I have access to an Apple Radeon 5770 card. I could potentially test with this to see what results I get. Is the Apple-specific 5770 usable on an Asus P8P67 PRO motherboard?
