You guys are hilarious. I care about performance only. Show me a battery of tests (10+ tests) that show that either:

4870 > GTX280 on average

or

4870CF > GTX280SLI on average

You won't because there aren't any. You may be able to point to one or two red herrings where that is the case. However if you average the results across many many games GTX280 still owns 4870 and SLI scales better across more games than CF currently does.

You guys remind me of the HD DVD fanboys who said HD DVD was better because it was cheaper. (we all know how that eventually turned out )

I don't care if you think AMD is more "efficient". Power consumption and heat say otherwise anyway.

Show me the FPS.
