that chart is very misleading in my opinion - at what res - and what games ?
put it this way - I had some money to spend and I was umming and arring whether to get an out of the box overclocked GTX285 or a 4890
I chose the Asus 4890

overall benchmark covering a load of games and different resolutions...
Sure the 4890 is moderatly faster in a good number of games, but overall when you test with 20 or so games theres not a huge amount in it.
