That spec chart is a lame fake....

AMD would never waste time positioning against both a GTX460 768Mb and 1gb part. The 768Mb part was dead on arrival as far as I'm concerned. Anyone who is in the know would pony up the extra $20 for the much improved performance of the 1gb.

This being said, if Barts XT isnt as least as good as a 5870, I will be disapoint son.
