Probably, but I doubt it's as good as your trifire 5850s
I've grown tired of the driver issues from release to release with AMD. I'm in the middle of a love / hate relationship with AMD. I like the performance of my 5850s cards, though I think AMD is losing focus of the crossfire customers with each driver release. The latest 11.2 drivers seem to lower framerates on most things. 11.1 and 11.1a just seemed like an attempt to rebrand the driver software. The 10s offered the wake from sleep issue.
When ATI was ATI, they just seemed more focused, solid and reliable to me. Now I'm not so sure...
