Are there any *reliable* benchmarks of the 285 yet?
Find any GTX280 reviews with the clocks at about (core/shader/memory) 648/1476/1242MHz and you'll have a fairly solid estimation.

just to make bigger gap
Though of course there are people with real issues, I occasionally have a hard time getting the latest catalyst update to install, but I'm used to issues it's part of being an enthusiast in my opinion.
